If I get my hands to close to a fire I get hot and move them further away. Identify the stimulus in this situation
- A.
Moving my hands away
- B.
Sensors in my skin sending a message to my brain about heat being uncomfortable
- C.
The heat of the fire
Correct Answer
C. The heat of the fireExplanation
In this situation, the stimulus is the heat of the fire. When the person's hands get close to the fire, the heat from the fire acts as a stimulus and causes the person to feel uncomfortable. As a result, they instinctively move their hands further away from the fire to avoid getting burnt. The heat of the fire triggers a response in the person's body, prompting them to take action and protect themselves from potential harm.Rate this question:

The following diagram is a picture of:
- A.
A stem cell
- B.
A nerve cell (also known as a neuron)
- C.
An egg cell (also known as a gamete)
Correct Answer
B. A nerve cell (also known as a neuron)Explanation
The diagram represents a nerve cell, also known as a neuron. Neurons are specialized cells that transmit electrical signals in the nervous system. They have a unique structure with a cell body, dendrites, and an axon. The image likely shows these distinct features, such as the long axon and branching dendrites, which are characteristic of nerve cells. Stem cells and egg cells have different structures and functions, so they can be ruled out as the correct answer. Therefore, the diagram most likely depicts a nerve cell.Rate this question:

The left and right hemispheres of the brain control different types of processes. Which of the following statements is correct?
- A.
The left side of the brain deals more with logical and mathematical processes
- B.
The left side of the brain deals more with creative and artistic processes
- C.
If the left sode of your brain dominates over the right, you will want to become an accountant
Correct Answer
A. The left side of the brain deals more with logical and mathematical processesExplanation
The left side of the brain deals more with logical and mathematical processes. This is because the left hemisphere of the brain is generally associated with analytical thinking, language processing, and logical reasoning. It is responsible for tasks such as problem-solving, calculations, and organizing information. On the other hand, the right hemisphere of the brain is more involved in creative and artistic processes, such as imagination, intuition, and visual-spatial skills.Rate this question:

What are the three main types of memory?
- A.
Short term, medium term and long term memory
- B.
Sensory, short term and long term memory
- C.
Short term, long term and permanent memory
Correct Answer
B. Sensory, short term and long term memoryExplanation
The correct answer is sensory, short term, and long term memory. Sensory memory is the initial stage where information from the senses is briefly stored. Short term memory holds information temporarily and has a limited capacity. Long term memory is where information is stored for a longer period of time, potentially indefinitely. These three types of memory work together to process and retain information.Rate this question:

Hormones in plants control growth and development as do those in animals. The hormone ethylene has the following function:
- A.
Releasing seeds from dormancy
- B.
Root and shoot growth
- C.
Fruit-ripening
Correct Answer
C. Fruit-ripeningExplanation
Ethylene is a hormone in plants that is responsible for the process of fruit-ripening. It triggers various physiological and biochemical changes in the fruit, such as softening, color change, and aroma production. Ethylene production increases as the fruit matures, and it helps to coordinate the ripening process by influencing the expression of genes involved in fruit ripening. This hormone is crucial for determining the optimal time for fruit harvest and plays a significant role in regulating the quality and shelf life of fruits.Rate this question:

One role of many hormones in animals is to maintain homeostasis. The best definition of homeostasis is:
- A.
The maintenance of constant and stable conditions within the body
- B.
The maintenance of wildly fluctuating conditions within the body
- C.
The maintenance of water levels within the body
Correct Answer
A. The maintenance of constant and stable conditions within the bodyExplanation
Homeostasis refers to the ability of an organism to maintain a stable internal environment despite external changes. This includes regulating various factors such as temperature, pH, blood sugar levels, and hormone levels within a narrow range. By maintaining constant and stable conditions, hormones play a crucial role in ensuring the proper functioning of bodily systems and overall health.Rate this question:

Insulin is a hormone which triggers the breakdown of complex sugars into glucose, which are used in the body to produce energy. If an person has trouble producing insulin, he/she suffers from the medical condition known as:
- A.
Lung Cancer
- B.
Diabetes
- C.
Multiple Sclerosis
Correct Answer
B. DiabetesExplanation
Insulin is a hormone that plays a crucial role in regulating blood sugar levels. It helps in the breakdown of complex sugars into glucose, which is then used by the body to produce energy. If a person has trouble producing insulin, it leads to an imbalance in blood sugar levels, resulting in the medical condition known as diabetes. Diabetes is characterized by high blood sugar levels and can lead to various complications if not properly managed.Rate this question:

When you turn on the light in a room that was dark, the pupils of your eyes contract. In the stimulus response model, what is the response in this scenario
- A.
Light being turned on
- B.
Rod cells in eyes convert light energy to an electrical signal which travels to the brain
- C.
Pupils contract
Correct Answer
C. Pupils contractExplanation
When light is turned on in a dark room, the pupils of our eyes contract. This is a response in the stimulus-response model. The stimulus in this scenario is the light being turned on, and the response is the contraction of the pupils. The pupils contract in order to regulate the amount of light entering the eyes and protect the sensitive retina from excessive light.Rate this question:

Which of the following is not a part of the brain?
- A.
Medulla
- B.
Cerebellum
- C.
Ceratonin
Correct Answer
C. CeratoninExplanation
Ceratonin is not a part of the brain. It is actually a neurotransmitter that is produced in the brain, specifically in the pineal gland. It is involved in regulating various functions such as mood, sleep, and appetite. However, it is not a physical part or structure of the brain itself. The medulla and cerebellum, on the other hand, are both parts of the brain. The medulla is located at the base of the brainstem and is responsible for controlling vital functions such as breathing and heart rate. The cerebellum is located at the back of the brain and is involved in coordinating movement and maintaining balance.Rate this question:

There are theories that state that birth order has a part to play in forming a person's personality- particularly if a child is born first in the family as opposed to those who are born later. First-born sibblings are often more conscientious and seek parental approval, whilst later born sibblings are often more laid-back and can be better negotiators. What do you think about this theory? There is no right or wrong answer to this question but you will be marked on the way that you support your argument with reasons and examples. (5 marks)

A man was stranded in a life raft at sea for a long period of time. The only food he had to eat was the fish he caught. Initially the man ate the fish flesh to survive, but did not eat the other parts as they tasted disgusting to him. As time went on, however he started to seek out the fish organs and eyes, which became tastier to him than the flesh. As it happens the organs and eyes are high in vital vitamins and minerals which are lacking in the fish flesh. What can this story tell us about the functioning of the brain? (2 marks)

What are the two main parts of the nervous system?
- A.
Muscles and blood
- B.
Central Nervous System and Peripheral Nervous System
- C.
Nerves and brain
Correct Answer
B. Central Nervous System and PeripHeral Nervous SystemExplanation
The correct answer is Central Nervous System and Peripheral Nervous System. The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, which are responsible for processing and coordinating information. The PNS includes all the nerves outside of the CNS, which transmit signals between the CNS and the rest of the body. This division allows for the efficient functioning of the nervous system and enables communication and control throughout the body.Rate this question:
