Anatomy

1. Which part of the male urinary system is responsible for producing seminal fluid?

Correct answer: C

Rationale: The correct answer is C: Prostate gland. The prostate gland is responsible for producing seminal fluid, which is a milky fluid that nourishes and protects sperm. The bladder stores urine, the urethra is a tube that carries urine from the bladder out of the body, and the kidney filters waste products from the blood to produce urine. The prostate gland, located beneath the bladder, plays a crucial role in male reproductive health by contributing to semen production. Understanding the functions of each part of the male urinary system is important for comprehending reproductive anatomy and physiology.

2. An object is moving in a circle at constant speed. Is there a net force acting on it?

Correct answer: A

Rationale: Even though the speed is constant, the direction is constantly changing, requiring a centripetal force to keep the object moving in a circle.

3. Which type of nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom?

Correct answer: C

Rationale: The incredibly powerful, strong nuclear force overcomes the repulsive electrostatic force between protons, binding them together and stabilizing the nucleus.

4. What is the term for the small air sacs in the lungs where gas exchange (oxygen and carbon dioxide) takes place?

Correct answer: B

Rationale: The correct answer is B: Alveoli. Alveoli are the small air sacs in the lungs where gas exchange occurs. Oxygen from the air we breathe diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. Bronchi (A) are the large airways that branch off the trachea (C) and lead into the lungs. Bronchioles (D) are smaller airways that branch off the bronchi. Understanding the structure and function of the respiratory system is important for comprehending how oxygen is taken in and carbon dioxide is removed from the body.

5. What is the term for a genetic disorder caused by a mutation in a mitochondrial gene?

Correct answer: D

Rationale: Rationale: A) Autosomal dominant disorder: This type of genetic disorder is caused by a mutation in one copy of an autosomal gene. It is not related to mitochondrial gene mutations. B) Autosomal recessive disorder: This type of genetic disorder is caused by mutations in both copies of an autosomal gene. It is not related to mitochondrial gene mutations. C) Sex-linked disorder: This type of genetic disorder is caused by mutations in genes located on the sex chromosomes (X or Y). It is not related to mitochondrial gene mutations. D) Mitochondrial disorder: Mitochondrial disorders are genetic disorders caused by mutations in genes located in the mitochondria, the energy-producing structures within cells. These disorders are inherited maternally and can affect various organs and systems in the body due to the role of mitochondria in energy production.

6. What is the formula to calculate kinetic energy?

Correct answer: a

Rationale: Kinetic energy is calculated using the formula KE = ½ × mass × velocity².
