Only ____________ involve the manipulation of independent variables.
- Correlational studies
- Case studies
- Studies using naturalistic observation
- Experiments
Correct Answer

A. Experiments

Explanation

Experiments involve the manipulation of independent variables. In an experiment, researchers deliberately manipulate one or more independent variables to observe the effects on the dependent variable. This allows them to establish cause-and-effect relationships between variables. In contrast, correlational studies examine the relationship between variables without manipulating them, case studies focus on a single individual or group without manipulating variables, and studies using naturalistic observation simply observe and describe behavior without manipulating variables. Therefore, only experiments involve the manipulation of independent variables.

Psychology arose in the 19th century from developments in a number of areas, primarily:
- Culture and philosophy
- Philosophy and religion
- Science and medicine
- Science and philosophy
Correct Answer

A. Science and philosophy

Explanation

Psychology emerged in the 19th century as a result of advancements in both science and philosophy. Scientific methods and principles were being applied to understand human behavior and mental processes, leading to the establishment of psychology as a scientific discipline. At the same time, philosophers were also exploring questions related to the mind, consciousness, and human nature, which contributed to the development of psychological theories and concepts. The combination of scientific inquiry and philosophical reflection played a crucial role in the formation and growth of psychology as a field of study.

People who live in cities often do not respond to night sounds while asleep. This is an example of:
- Latent learning
- Classical conditioning
- Operant conditioning
- Habituation
Correct Answer

A. Habituation

Explanation

Habituation refers to the process of becoming accustomed to a stimulus over time, resulting in a decreased response to it. In this case, people who live in cities are exposed to various night sounds on a regular basis, causing them to become habituated to these sounds while asleep. As a result, their response to these sounds diminishes, allowing them to continue sleeping undisturbed. This demonstrates the concept of habituation as the explanation for why city dwellers often do not respond to night sounds while asleep.

Neurons are made up of:
- Interneurons, nuclei, and dendrites
- Sensory and motor processes
- Glial cells
- Cell body, axon, and dendrites
Correct Answer

A. Cell body, axon, and dendrites

Explanation

Neurons are the basic building blocks of the nervous system and are composed of three main parts: the cell body, axon, and dendrites. The cell body contains the nucleus and other organelles necessary for the neuron's functioning. The axon is a long, slender projection that carries electrical signals away from the cell body to other neurons or muscles. Dendrites are shorter, branch-like projections that receive incoming signals from other neurons. Together, these three components allow neurons to transmit and process information throughout the body.

Grace was out on a crowded dance floor when the person dancing next to her accidentally kicked her in the leg. Which type of neuron carried the pain information from her leg to the central nervous system?
- Interneurons
- Primary Neurons
- Motor Neurons
- Sensory Neurons
Correct Answer

A. Sensory Neurons

Explanation

Sensory neurons are responsible for carrying pain information from the leg to the central nervous system. These neurons are specialized to detect and transmit sensory information, including pain, from various parts of the body to the brain. In this case, when Grace was kicked in the leg, the sensory neurons in her leg would have detected the pain stimulus and transmitted the information to the central nervous system, allowing her to perceive the pain sensation.

In psychological research, the term generalization refers to:
- Obtaining a broad understanding of how different variables are related to eachother.
- Adding the results from one study to those from other studies
- How significant the results of the statistical analysis are
- Concluding that the results obtained from a sample can also be applied to the larger population
Correct Answer

A. Concluding that the results obtained from a sample can also be applied to the larger population

Explanation

The term generalization in psychological research refers to the process of applying the results obtained from a sample to the larger population. This means that researchers can draw conclusions about the entire population based on the findings from a smaller group. Generalization allows researchers to make broader statements and predictions about human behavior and psychological processes. It is an important aspect of research as it helps to establish the external validity and generalizability of the findings.

The fact that male peacocks have evolved large tail feathers (even though large feathers appear to be an impediment for survival) is best explained by:
- Large feathers can be used to protect the nest
- Evolution through sexual selection
- Evolution through natural selection
- Genetic drift
Correct Answer

A. Evolution through sexual selection

Explanation

The evolution of large tail feathers in male peacocks can be best explained by evolution through sexual selection. This theory suggests that certain traits evolve because they increase an individual's chances of mating and reproducing, even if they may have negative effects on survival. In the case of peacocks, the large and colorful tail feathers are attractive to females and play a crucial role in mate selection. Therefore, over time, males with larger and more elaborate tail feathers have a higher chance of mating and passing on their genes, leading to the evolution of this trait.

Natural selection has favoured species that reproduce sexually because sexual reproduction:
- Pleasurable, which is reinforcing
- Leads to a longer life span and more variability in behaviour
- Produces organisms that have the capacity for thinking and language
- Leads to genetic diversity, which is adaptive
Correct Answer

A. Leads to genetic diversity, which is adaptive

Explanation

Sexual reproduction leads to genetic diversity, which is adaptive. This is because sexual reproduction involves the exchange and recombination of genetic material between two parents, resulting in offspring that have a combination of traits from both parents. This genetic diversity allows for a greater range of variation within a population, which can be beneficial for survival and adaptation to changing environments. It increases the chances of some individuals having traits that are advantageous in certain conditions, ensuring the survival of the species as a whole.

The placement of our ears on opposite sides of the head is crucial to our ability to:
- Figure out where a sound is coming from
- Identify the pitch of a sound
- Judge how far away a sound is
- Determine how loud a sound is
Correct Answer

A. Figure out where a sound is coming from

Explanation

The placement of our ears on opposite sides of the head allows us to figure out where a sound is coming from. This is because sound waves reach each ear at slightly different times and intensities, allowing our brain to process this information and determine the direction of the sound source.

- A small "hole" in a particular region of the left visual field
- Slight weakness in the muscles that control the contralateral eye
- A tiny lesion is unlikely to have any effects on vision
- A small "hole" in a particular region of the right visual field
Correct Answer

A. A small "hole" in a particular region of the right visual field

Explanation

The left primary visual cortex is responsible for processing visual information from the right visual field. Therefore, a lesion in this area would result in a small "hole" in a particular region of the right visual field.

Essay questions tend to be more difficult than multiple choice because with an essay quesiton:
- Recall is required, rather than recognition
- There is more proactive inhibition
- There is more interference possible
- Encoding rehearsal is more effortful
Correct Answer

A. Recall is required, rather than recognition

Explanation

Essay questions tend to be more difficult than multiple-choice questions because they require recall rather than recognition. In essay questions, students need to actively retrieve information from their memory and generate a response, whereas in multiple-choice questions, they only need to recognize the correct answer among the given options. This recall process is more challenging as it requires a deeper understanding of the material and the ability to organize and articulate thoughts effectively. In contrast, recognition tasks rely on familiarity and can be aided by cues or context provided in the options.

The central nervous system (CNS) consists of the ____________ and the ____________.
- Sympathetic nervous system; parasympathetic nervous system
- Brain; spinal cord
- Brain, peripheral nervous system
- Left cerebral hemisphere; right cerebral hemisphere
Correct Answer

A. Brain; spinal cord

Explanation

The central nervous system (CNS) is made up of the brain and the spinal cord. These two components work together to process and coordinate information throughout the body. The brain is responsible for higher-level functions such as thinking, memory, and emotions, while the spinal cord acts as a pathway for transmitting signals between the brain and the rest of the body. Together, they form the central command center of the nervous system, controlling and regulating various bodily functions.

The Gestalt law of similarity predicts that:
- Similar objects are more easily perceived than different objects
- Similar elements are perceptually grouped together
- Similar objects are closer to each other than different objects
- Near objects are perceived as being smaller than distant objects
Correct Answer

A. Similar elements are perceptually grouped together

Explanation

The Gestalt law of similarity states that similar elements are perceptually grouped together. This means that when presented with a group of objects or elements, our brain tends to perceive those that are similar in terms of shape, color, size, or other attributes as belonging to the same group or category. This grouping helps us organize and make sense of the visual information we receive, allowing us to perceive patterns and relationships between objects.

The first step of the scientific method specifies that a researcher:
- Design the study
- Formulate a hypothesis
- Determine the subjects that he/she would like to use in the experiment
- Collect the data for the study
Correct Answer

A. Formulate a hypothesis

Explanation

The first step of the scientific method is to formulate a hypothesis. This involves identifying a specific question or problem that the researcher wants to investigate and then proposing a possible explanation or prediction for that question or problem. By formulating a hypothesis, the researcher is able to guide their study and design experiments or collect data that will help them test and evaluate the validity of their hypothesis. This step is crucial as it sets the foundation for the entire scientific research process.

Information from the right visual field is conveyed:
- To the left visual cortex in the parietal lobe
- To the right visual cortex in the occipital lobe
- To the left visual cortex in the occipital lobe
- To the right visual cortex in the parietal lobe
Correct Answer

A. To the left visual cortex in the occipital lobe

Explanation

Information from the right visual field is conveyed to the left visual cortex in the occipital lobe because the visual pathways in the brain cross over at the optic chiasm. This means that the right visual field is processed by the left side of the brain. The occipital lobe is responsible for processing visual information, so the correct answer is that information from the right visual field is conveyed to the left visual cortex in the occipital lobe.

Suppose you stared at a blue balloon, then shifted your eyes to a white surface and saw a yellow afterimage of the balloon. This afterimage would be explained by the fact that retinal neurons that respond most to blue-appearing light ____________, while those that respond to yellow-appearing light ____________.
- Became fatigued; still responded strongly
- Respond subtractively; respond additively
- Continue to respond strongly; respond equally strongly
- Continue to respond strongly; add their excitation to that of the "blue" neurons
Correct Answer

A. Became fatigued; still responded strongly

Explanation

The afterimage of the yellow balloon on the white surface suggests that the retinal neurons that respond most to blue-appearing light became fatigued, while those that respond to yellow-appearing light still responded strongly. This is because prolonged exposure to a particular color can cause the corresponding retinal neurons to become fatigued, resulting in an afterimage of the complementary color. In this case, the blue-responding neurons became fatigued, leading to the perception of a yellow afterimage. However, the yellow-responding neurons remained responsive, which is why they still responded strongly to the white surface.

After being in a car accident, Geoff began having problems concetrating, and paying attention to things. His wife noticed that this normally tidy man was messy and disorganized, and a colleague at work recently complained that Geoff behaved inappropriately towards her. Which of the following lobes was most likely damaged?
- Frontal
- Parietal
- Occipital
- Temporal
Correct Answer

A. Frontal

Explanation

After a car accident, Geoff's change in behavior and cognitive abilities suggest damage to the frontal lobe. The frontal lobe is responsible for executive functions such as attention, concentration, organization, and impulse control. Geoff's difficulty in concentrating, being messy and disorganized, and behaving inappropriately towards his colleague align with frontal lobe dysfunction. The other lobes (parietal, occipital, and temporal) are not primarily associated with these symptoms.

Mean is to ____________ as standard deviation is to _____________.
- Central tendency; variability
- Inferential statistics; descriptive statistics
- Descriptive statistics; inferential statistics
- Variability; relations
Correct Answer

A. Central tendency; variability

Explanation

The mean is a measure of central tendency, representing the average value of a set of data. Similarly, the standard deviation is a measure of variability, indicating how spread out the data points are from the mean. Therefore, the relationship between mean and standard deviation can be described as central tendency and variability.

Research on eyewitness testimony has shown that:
- Women are generally more accurate eyewitnesses than men
- Eyewitness testimony is more accurate because the event is encoded under stressful situations
- Eyewitness testimony is highly resistant to leading questions
- Retrieval cues can bias eyewitness accounts
Correct Answer

A. Retrieval cues can bias eyewitness accounts

Explanation

Research on eyewitness testimony has shown that retrieval cues can bias eyewitness accounts. This means that the way information is retrieved from memory can be influenced by external cues, leading to inaccuracies in the eyewitness's recollection of the event. These cues can include leading questions, suggestive language, or even the presence of other people who may inadvertently influence the witness's memory. This finding highlights the importance of careful questioning techniques and the need to consider the potential impact of retrieval cues on the accuracy of eyewitness testimony.

Azmy is participating in an experiment in which he just heard a list of 15 words, and is now being asked to recall them. He will probably
- Remember lots of items from the middle and end of the list, not so many from the beginning
- Remember lots of items from the beginning of the list, not so many from the middle and end
- Remember lots of items from the end of the list, not so many from the beginning and middle
- Remember lots of items from the beginning and end of the lsit, not so many from the middle
Correct Answer

A. Remember lots of items from the beginning and end of the lsit, not so many from the middle

Explanation

This phenomenon is known as the serial position effect. The beginning of the list is associated with the primacy effect, where items are more likely to be transferred into long-term memory. The end of the list is associated with the recency effect, where items are still in short-term memory. The middle items are more likely to be forgotten as they are neither in the beginning nor at the end. Therefore, Azmy is more likely to remember items from the beginning and end of the list, but not so many from the middle.

Through their research on human responses to physical stimuli, both von Helmholtz and Fechner contributed to the beginnings of:
- Comparative psychology
- Materialism
- Rationalism
- Psychophysics
Correct Answer

A. Psychophysics

Explanation

Von Helmholtz and Fechner's research on human responses to physical stimuli laid the groundwork for psychophysics. Psychophysics is the branch of psychology that studies the relationship between physical stimuli and the sensations and perceptions they produce. By examining how humans perceive and respond to different stimuli, von Helmholtz and Fechner helped establish the field of psychophysics, which continues to explore the complex relationship between the physical world and our subjective experiences.

Visual acuity is sharpest when images cast by environmental stimuli fall directly on the fovea because:
- Each cone synapses directly onto a single ganglion cell and there is a concentration of cones in the fovea
- The fovea has no blind spot
- The distance between the retina and the optic nerve is minimized at the fovea
- There are fewer bipolar and ganglion cells in the area surrounding the fovea than there are in the area surrounding the retina's periphery
Correct Answer

A. Each cone synapses directly onto a single ganglion cell and there is a concentration of cones in the fovea

Explanation

The fovea is the central area of the retina where visual acuity is the sharpest. This is because each cone in the fovea directly connects to a single ganglion cell, allowing for a more precise transmission of visual information. Additionally, the fovea contains a high concentration of cones, which are responsible for color vision and detailed visual perception. This concentration of cones in the fovea further enhances visual acuity in this area.

__________ is a learning procedure that utilizes reinforcement to guide a response in closer and closer approximations to a desired behaviour.
- Classical Conditioning
- Shaping
- Habituation
- Partial Reinforcement
Correct Answer

A. Shaping

Explanation

Shaping is a learning procedure that utilizes reinforcement to guide a response in closer and closer approximations to a desired behavior. This means that instead of waiting for the desired behavior to occur naturally, shaping involves reinforcing small steps or behaviors that are similar to the desired behavior, gradually shaping the individual towards the desired behavior. Through this process, the individual learns and develops the desired behavior through reinforcement and repetition.

For sound waves, amplitude is to _____________ as frequency is to ______________.
- Pitch; loudness
- Loudness; timbre
- Timbre; pitch
- Loudness; pitch
Correct Answer

A. Loudness; pitch

Explanation

Amplitude refers to the intensity or strength of a sound wave, similar to how loudness refers to the volume or perceived intensity of a sound. On the other hand, frequency refers to the number of cycles or vibrations per second in a sound wave, which determines the pitch or how high or low a sound is perceived. Therefore, the correct analogy is that amplitude is to loudness as frequency is to pitch.

The receptors for hearing are:
- The fluid-filled ducts in the cochlea
- In the auditory nerve
- The basilar and tectorial membranes
- Hair cells on the basilar membrane
Correct Answer

A. Hair cells on the basilar membrane

Explanation

The receptors for hearing are hair cells on the basilar membrane. These hair cells are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. The basilar membrane is a structure within the cochlea, which is part of the inner ear. The fluid-filled ducts in the cochlea, the auditory nerve, and the basilar and tectorial membranes are all important components of the auditory system, but they do not directly function as the receptors for hearing.

Suppose that you have just finished working out and decide to take a shower. You are also expecting an important phone call, and so decide that you will listen extra carefully for the ringing of the phone. Two or three times, you pop your head out of the shower thinking that you hear the phone, but it didn't really ring. Your experience of listening to the phone has to do with:
- Just-noticible differences
- Your response bias
- Your absolute threshold
- Weber's fraction
Correct Answer

A. Your response bias

Explanation

The correct answer is "your response bias". In this scenario, the person's expectation of an important phone call causes them to be more alert and attentive to any potential ringing sound. As a result, they may perceive non-existent ringing sounds and pop their head out of the shower. This is an example of a response bias, where their expectation influences their perception and response to a stimulus. The other options, such as just noticeable differences, absolute threshold, and Weber's fraction, do not accurately explain the person's experience in this situation.

The sensory homunculus in primary somatosensory cortex:
- Involves one cortical cell per square mm of skin surface
- Overrepresents some parts of the body and underrepresents others
- Has a very large torso, and tiny hands and feet
- Is impervious to change in adult animals, even after extensive training
Correct Answer

A. Overrepresents some parts of the body and underrepresents others

Explanation

The sensory homunculus in the primary somatosensory cortex represents different body parts based on their sensitivity and importance. It overrepresents body parts that have a high density of sensory receptors and require precise discrimination, such as the hands, lips, and face. On the other hand, it underrepresents body parts with lower sensory acuity, such as the torso and limbs. This representation is not fixed and can change with experience and training, contrary to the statement that it is impervious to change in adult animals.

Which of the following is the best example of operant conditioning?
- A student studies for her math test and received a mark of 90%. She then studies extra hard for the next exam.
- Two boys imitate a professional wrestler they view on television.
- A young child becomes fearful whenever seeing the babysitter.
- A child continues to pick on his sister, despite receiving repeated time-outs.
Correct Answer

A. A student studies for her math test and received a mark of 90%. She then studies extra hard for the next exam.

Explanation

This is the best example of operant conditioning because the student's behavior of studying extra hard for the next exam is a result of receiving positive reinforcement (getting a mark of 90%). The positive reinforcement of receiving a high mark increases the likelihood of the behavior (studying extra hard) being repeated in the future.

How does perception differ from sensation?
- Sensory neurons exhibit adaptation while perceptual neurons do not
- They don't differ; the two terms are synonymous
- Sensation requires no experience, whereas perception implies prior experience which gives a sensation its meaning
- Sensation involves active arousal whereas perception is passive
Correct Answer

A. Sensation requires no experience, whereas perception implies prior experience which gives a sensation its meaning

Explanation

Sensation refers to the process of detecting stimuli through our senses, while perception involves the interpretation and understanding of those sensations based on our prior experiences. Sensation is a basic physiological process that occurs without any prior knowledge or experience. On the other hand, perception relies on our previous experiences, knowledge, and expectations to give meaning to the sensations we experience. Therefore, the answer correctly states that sensation requires no experience, whereas perception implies prior experience which gives a sensation its meaning.

Dr. Lemieux wants to determine if a group of participants reading on computer screens will read more pages of text in 1 hour than a group of participants reading on paper. She assigns students sitting at the front to be the "computer" condition, and the students sitting at the back to be the "paper" condition. In this experiment, seating location is:
- The independent variable
- A confounding variable
- The dependent variable
- An operational definition
Correct Answer

A. A confounding variable

Explanation

Seating location is considered a confounding variable in this experiment because it is not the intended independent variable being studied (which is the medium of reading - computer screens or paper). Seating location may have an impact on the participants' reading speed or comprehension, which could potentially influence the results. It is important to control for confounding variables in order to accurately determine the effect of the independent variable on the dependent variable.

Which of the following is TRUE about hemispheric specialization?
- The left hemisphere receives sensory information from the left side of the body, and the right hemisphere from the right side
- The left hemisphere is generally specialized for language function, while the right hemisphere seems to be better at appreciating spatial relationships among objects
- The right hemisphere generally has no language ability
- The left hemisphere is logical and analytic, whereas the right hemisphere is creative and intuitive
Correct Answer

A. The left hemisphere is generally specialized for language function, while the right hemisphere seems to be better at appreciating spatial relationships among objects

Explanation

The left hemisphere is generally specialized for language function, while the right hemisphere seems to be better at appreciating spatial relationships among objects. This is supported by research on hemispheric specialization, which has shown that language processing, such as speech production and comprehension, is primarily localized in the left hemisphere. On the other hand, the right hemisphere is involved in processing visual-spatial information and is better at tasks like recognizing faces and understanding spatial relationships between objects. This division of functions between the two hemispheres is known as hemispheric specialization or lateralization.

A recessive allele will influence the expression of a trait only when it:
- Forms a heterozygous gene combination with another recessive allele
- Is paired with a dominant, but weak allele
- Is paired with another recessive allele
- Forms a homozygous gene combination with a dominant allele
Correct Answer

A. Is paired with another recessive allele

Explanation

When a recessive allele is paired with another recessive allele, it will influence the expression of a trait. This is because recessive alleles are only expressed when there are no dominant alleles present. In a homozygous recessive gene combination, both alleles are recessive, and therefore the trait associated with the recessive allele will be expressed.

Psychology is most closely related to:
- Biology
- Chemistry
- Sociology
- Philosophy
Correct Answer

A. Biology

Explanation

Psychology is most closely related to biology because both fields study the human mind and behavior. Biology explores the biological basis of behavior, including the brain, genetics, and hormones, while psychology focuses on understanding and explaining human thoughts, emotions, and actions. The two disciplines often intersect, as psychological processes are influenced by biological factors. For example, studying how neurotransmitters affect mood and behavior is a common area of research in both fields. Understanding the biological foundations of psychology is crucial for comprehending human behavior and mental processes.

Which of the following statements is FALSE regarding human sexual behaviour?
- Unmarried women tend to seek casual sexual relationships
- Men are more likely to seek diversity in their sexual relationships than women
- Men tend to be more promiscuous than women
- Human sexual behaviour is subject to strong cultural influences
Correct Answer

A. Unmarried women tend to seek casual sexual relationships

Explanation

The statement "Unmarried women tend to seek casual sexual relationships" is false. Research suggests that both men and women, regardless of marital status, have similar desires for casual sexual relationships. The idea that unmarried women are more likely to seek casual sexual relationships is a stereotype that is not supported by empirical evidence.

Which of the following is FALSE about brain plasticity?
- The environmental richness of the environment in which they grow up is positively correlated with the structural complexity and size of rats' brains
- After childhood, the functional organization of the human brain is unchangeable
- All learning and memory requires a physical change in the brain
- Early-life stress can produce physical changes in the brain
Correct Answer

A. After childhood, the functional organization of the human brain is unchangeable

Explanation

The statement that "After childhood, the functional organization of the human brain is unchangeable" is FALSE. Brain plasticity refers to the brain's ability to change and adapt throughout life. Even after childhood, the brain can still reorganize its neural connections and modify its functional organization in response to learning, experiences, and environmental influences. This phenomenon is known as neuroplasticity and has been observed in various studies. Therefore, the functional organization of the human brain is not fixed and can be modified throughout adulthood.

As sleep cycles progress over the course of an average night, the amount of time spent in REM sleep:
- Becomes zero (REM eventually drops out of the sleep cycle)
- Increases
- Decreases
- Becomes 100% (the last few hours of sleep before regular waking time are entirely REM)
Correct Answer

A. Increases

Explanation

As sleep cycles progress over the course of an average night, the amount of time spent in REM sleep increases. This is because REM sleep, also known as rapid eye movement sleep, is a stage of sleep characterized by vivid dreaming and heightened brain activity. REM sleep typically occurs in shorter intervals at the beginning of the night and becomes longer and more frequent as the night progresses. Therefore, the correct answer is that the amount of time spent in REM sleep increases over the course of the night.

The visual information is first sent via the optic nerve to the thalamus. The thalamus acts as a relay station and processes the information before sending it to the primary visual cortex, which is located in the occipital lobe. The primary visual cortex is responsible for further processing and interpreting the visual information.

Which of the following is FALSE?
- Outer hair cells deteriorate with age, causing hearing loss
- Most hearing loss results from damage to the cilia (hair cells)
- Hearing loss can occur with a few exposures to very loud noises (rock concerts)
- Hearing loss repairs itself over time as the hair cells regenerate
Correct Answer

A. Hearing loss repairs itself over time as the hair cells regenerate

Most traits and disorders are caused by:
- A single gene
- A single gene and the environment
- Multiple genes (polygenic)
- Multiple genes and the environment
Correct Answer

A. Multiple genes and the environment

Explanation

Most traits and disorders are caused by a combination of multiple genes and the environment. This means that there is not just one gene responsible for a particular trait or disorder, but rather a complex interaction between multiple genes and environmental factors. Genetic variations in multiple genes can contribute to the development of a trait or disorder, but the expression of these genes can also be influenced by environmental factors such as diet, lifestyle, and exposure to toxins. Therefore, both genetic and environmental factors play a role in determining the manifestation of traits and disorders.

The CNS is made up of two general classes of cells:
- Neurons and glia
- Afferent and efferent
- Hormones and neurotransmitters
- Somatosensory and skeletal
Correct Answer

A. Neurons and glia

Explanation

The central nervous system (CNS) is composed of two general classes of cells: neurons and glia. Neurons are responsible for transmitting electrical signals and information throughout the body, while glia provide support and protection to the neurons. Together, these cells play a crucial role in the functioning of the CNS, allowing for the processing and coordination of sensory information, motor control, and cognitive functions.

An organism's phenotype is the result of:
- The influence of environmental influences and experiences
- Its genotype
- The reproductive success of its parents
- The interaction of its genotype with the environment
Correct Answer

A. The interaction of its genotype with the environment

Explanation

An organism's phenotype is the observable characteristics or traits that are determined by both its genotype (genetic makeup) and the environment it interacts with. While the genotype provides the genetic instructions, the environment plays a crucial role in how those genes are expressed. Environmental factors such as nutrition, temperature, and social interactions can influence the development and expression of certain traits. Therefore, the interaction between an organism's genotype and the environment is what ultimately shapes its phenotype.

Which of the following is NOT true about sleep?
- Stages 3 and 4 are the deepest stages of sleep, when regular, slow waves are evident on an EEG
- During stage 4 sleep, our skeletal muscles are almost completely inactive
- REM sleep happens once per night
- As you transition through the stages of sleep from stage 4 to stage 2, your neural activity oscillates at faster and faster frequencies
Correct Answer

A. REM sleep happens once per night

Explanation

During REM sleep, our skeletal muscles are almost completely inactive. This is because REM sleep is characterized by rapid eye movements and vivid dreaming, while our skeletal muscles experience temporary paralysis, known as REM atonia. This prevents us from physically acting out our dreams and potentially harming ourselves or others. Therefore, the statement "REM sleep happens once per night" is not true, as we cycle through multiple REM and non-REM sleep stages throughout the night.
