1.
Which organ system(s) major function involves communication and control? Mark all that apply.
Correct Answer(s)
A. Endocrine
D. Nervous
Explanation
The endocrine and nervous systems are both involved in communication and control within the body. The endocrine system uses hormones to communicate and regulate various bodily functions, while the nervous system uses electrical signals to transmit information and control body processes. Both systems work together to maintain homeostasis and coordinate the body's response to internal and external stimuli. The cardiovascular and lymphatic systems do not have a major function in communication and control, so they are not correct answers.
2.
Which organ system(s) major function involves distribution and elimination? Mark all that apply.
Correct Answer(s)
A. Respiratory
B. Digestive
D. Urinary
Explanation
The respiratory system's major function involves the distribution of oxygen to the body and the elimination of carbon dioxide. The digestive system's major function involves the distribution of nutrients to the body and the elimination of waste products. The urinary system's major function involves the distribution of urine for elimination of waste products. Therefore, the correct answer is respiratory, digestive, and urinary.
3.
Which organ system(s) major function involves transportation and immunity? Mark all that apply.
Correct Answer(s)
B. Cardiovascular
C. LympHatic
Explanation
The cardiovascular system is responsible for the transportation of oxygen, nutrients, hormones, and waste products throughout the body. It consists of the heart, blood vessels, and blood. The lymphatic system is involved in immunity and helps to transport lymph, a fluid containing white blood cells, throughout the body. It also plays a role in filtering out harmful substances and fighting infections. Therefore, both the cardiovascular and lymphatic systems have major functions involving transportation and immunity.
4.
Which organ system(s) major function involves framework and movement? Mark all that apply.
Correct Answer(s)
B. Muscular
D. Skeletal
Explanation
The muscular and skeletal systems both play major roles in framework and movement. The muscular system is responsible for generating force and movement, while the skeletal system provides the framework and support for the body, as well as allowing for movement through its joints.
5.
Which organ system(s) major function involves coverings and protection? Mark all that apply.
Correct Answer
A. Integumentary
Explanation
The integumentary system is responsible for covering and protecting the body. It includes the skin, hair, nails, and glands. The skin acts as a barrier, protecting the body from external factors such as bacteria, UV radiation, and dehydration. It also helps regulate body temperature and contains sensory receptors for touch, pain, and pressure. Therefore, the integumentary system's major function involves coverings and protection.
6.
Which organ system(s) major function involves the human life cycle? Mark all that apply.
Correct Answer
B. Reproductive
Explanation
The reproductive system is responsible for the human life cycle as it involves the production of gametes (sperm and eggs), fertilization, pregnancy, and childbirth. It is involved in the creation of new life and the continuation of the species.
7.
This is the study of the structure of an organism such as humans.
Correct Answer
A. Anatomy
Explanation
Anatomy is the study of the structure of organisms, including humans. It focuses on the arrangement and relationships of body parts, organs, and tissues. This field of study helps in understanding the physical makeup of living organisms and how different parts of the body work together. Anatomy is essential for medical professionals to diagnose and treat diseases, perform surgeries, and develop new medical interventions.
8.
This is the study of tissue.
Correct Answer
D. Histology
Explanation
Histology is the study of tissues. It involves examining the microscopic structure of tissues and cells, as well as their organization and functions within the body. This field of study helps in understanding the different types of tissues, their composition, and how they contribute to overall bodily functions.
9.
This is the study of cells.
Correct Answer
C. Cytology
Explanation
Cytology is the study of cells, which involves examining their structure, function, and behavior. It focuses on the microscopic analysis of cells and their components, such as organelles and molecules. This field helps in understanding the basic building blocks of life and their interactions, which is crucial for various scientific and medical advancements.
10.
This is the study of the nature of living organisms.
Correct Answer
B. pHysiology
Explanation
Physiology is the study of the nature of living organisms, specifically focusing on how their body systems and organs function. It involves examining the processes and mechanisms that occur within the body, such as digestion, respiration, and circulation. This field of study helps us understand how living organisms maintain homeostasis and adapt to their environment.
11.
This is the study of disease.
Correct Answer
E. Pathology
Explanation
Pathology is the study of disease, including the causes, mechanisms, and effects of diseases on the body. It involves examining tissues, organs, and bodily fluids to understand the nature and progression of diseases. Pathologists use various techniques and tests to diagnose diseases and provide important information for treatment and prevention. They play a crucial role in identifying and understanding the underlying causes of diseases, which is essential for developing effective therapies and interventions.
12.
Which term refers to fatty tissue throughout the body?
Correct Answer
C. Adipose
Explanation
Adipose refers to fatty tissue throughout the body. It is a type of connective tissue that stores energy in the form of fat cells. Adipose tissue is found beneath the skin, around internal organs, and in bone marrow. It serves as insulation, cushioning, and a source of stored energy for the body.
13.
A single hereditary unit consisting of a section of DNA that transmits and determines a hereditary trait by coding for a specific protein is called a ___.
Correct Answer
C. Gene
Explanation
A gene is a single hereditary unit consisting of a section of DNA that transmits and determines a hereditary trait by coding for a specific protein. It carries the instructions for making proteins, which are essential for the functioning and development of an organism. Genes are responsible for the expression of traits and characteristics in an individual.
14.
This refers to the complete set of genetic information inside the nuclei of each of the body’s trillions of cells.
Correct Answer
D. Genome
Explanation
The term "genome" refers to the complete set of genetic information inside the nuclei of each of the body's trillions of cells. It includes all the genes present in an organism, along with non-coding DNA sequences. The genome is responsible for determining the characteristics and traits of an individual, such as their phenotype. Chromosomes are structures within the nucleus that contain genes, while genes are specific segments of DNA that code for proteins and contribute to traits. Therefore, "genome" is the correct answer as it encompasses all the genetic information in an organism.
15.
The microscopic bodies that carry the instructions for making multiple proteins that determine hereditary characteristics are called ___.
Correct Answer
A. Chromosomes
Explanation
Chromosomes are the microscopic bodies that carry the instructions for making multiple proteins that determine hereditary characteristics. They contain genes, which are segments of DNA that code for specific proteins. These proteins determine the traits and characteristics of an individual, such as hair color, eye color, and height. Therefore, chromosomes play a crucial role in the transmission of genetic information and the inheritance of traits from one generation to the next.
16.
The physical appearance or type of makeup of an individual is called a ___.
Correct Answer
B. pHenotype
Explanation
Phenotype refers to the physical characteristics or traits of an individual, including their appearance or makeup. This can include things like eye color, hair type, and height. Chromosomes, genes, and genomes are all related to genetic information, but they do not specifically refer to the physical appearance of an individual.
