Which of the following is NOT a type of genetic mutation:

  1. Substitution

  2. Deletion

  3. Insertion

  4. Transversion


Correct Option: D
Explanation:

Transversion is not a type of genetic mutation. Substitution, deletion, and insertion are all types of genetic mutations.

  1. Bacteria

  2. Virus

  3. Fungus

  4. Protozoan


Correct Option:
Explanation:

Bacteria, viruses, fungi, and protozoa are all examples of infectious agents.

What is the role of the immune system in disease:

  1. To protect the body from infection

  2. To repair damaged cells

  3. To regulate the body's temperature

  4. To produce hormones


Correct Option: A
Explanation:

The primary role of the immune system is to protect the body from infection.

Which of the following is an example of an autoimmune disease:

  1. Type 1 diabetes

  3. Rheumatoid arthritis

  4. All of the above


Correct Option: D
Explanation:

Type 1 diabetes, multiple sclerosis, and rheumatoid arthritis are all examples of autoimmune diseases.

What is the term for a genetic disorder caused by a mutation in a single gene:

  1. Monogenic disorder

  2. Polygenic disorder

  3. Multifactorial disorder

  4. Chromosomal disorder


Correct Option: A
Explanation:

A genetic disorder caused by a mutation in a single gene is called a monogenic disorder.

Which of the following is an example of a polygenic disorder:

  1. Heart disease

  4. All of the above


Correct Option: D
Explanation:

Heart disease, cancer, and diabetes are all examples of polygenic disorders.

What is the term for a genetic disorder caused by a mutation in multiple genes:

  1. Monogenic disorder

  2. Polygenic disorder

  3. Multifactorial disorder

  4. Chromosomal disorder


Correct Option: B
Explanation:

A genetic disorder caused by a mutation in multiple genes is called a polygenic disorder.

Which of the following is an example of a multifactorial disorder:

  1. Infectious disease

  2. Non-infectious disease

  3. Genetic disease

  4. Autoimmune disease


Correct Option: A
Explanation:

A disease caused by an infectious agent is called an infectious disease.

Which of the following is an example of an infectious disease:

  1. Common cold

  2. Influenza

  3. Measles

  4. All of the above


Correct Option: D
Explanation:

Common cold, influenza, and measles are all examples of infectious diseases.

What is the term for a disease that is not caused by an infectious agent:

  1. Infectious disease

  2. Non-infectious disease

  3. Genetic disease

  4. Autoimmune disease


Correct Option: B
Explanation:

A disease that is not caused by an infectious agent is called a non-infectious disease.

Which of the following is an example of a non-infectious disease:

  1. Heart disease

  2. Cancer

  3. Diabetes

  4. All of the above


Correct Option: D
Explanation:

Heart disease, cancer, and diabetes are all examples of non-infectious diseases.

What is the term for a disease that is caused by a defect in the immune system:

  1. Infectious disease

  2. Non-infectious disease

  3. Genetic disease

  4. Autoimmune disease


Correct Option: D
Explanation:

A disease that is caused by a defect in the immune system is called an autoimmune disease.
