1. Which of the following is NOT a function of progesterone in the female reproductive system?

Correct answer: A

Rationale: Progesterone plays a key role in the regulation and preparation of the endometrial lining of the uterus for potential pregnancy. It also inhibits contractions of the uterus as the ovum is released and stimulates milk production in the breasts. However, the expression of secondary sexual characteristics, such as enlarged breasts, is primarily influenced by estrogen, not progesterone. Therefore, choice A is the correct answer as it is not a function directly attributed to progesterone in the female reproductive system.

2. What is the primary function of the large intestine?

Correct answer: B

Rationale: The correct answer is B. The primary function of the large intestine is to absorb water from digested food and form feces for elimination. It does not primarily digest food, absorb proteins, or regulate blood pressure. Choice A is incorrect because the large intestine does not digest food but rather absorbs nutrients and water. Choice C is incorrect as the absorption of proteins primarily occurs in the small intestine. Choice D is incorrect as the regulation of blood pressure is not a primary function of the large intestine.

3. What is the formula to calculate kinetic energy?

Correct answer: A

Rationale: Kinetic energy is the energy an object possesses due to its motion. The formula to calculate kinetic energy is KE = 0.5 × mass × velocity^2, which can also be written as KE = mass × (velocity)^2. Therefore, the correct formula is Kinetic Energy = Mass × Velocity. Choice B is incorrect because it represents the work formula. Choice C is incorrect as it represents the formula for work done. Choice D is incorrect as it does not accurately represent the formula for calculating kinetic energy.

4. What does antidiuretic hormone (ADH) help the kidneys regulate?

Correct answer: C

Rationale: Antidiuretic hormone (ADH) helps the kidneys regulate urine output by controlling water reabsorption. ADH acts on the kidneys to increase the reabsorption of water, leading to a decrease in urine output. This helps the body conserve water and maintain proper fluid balance. ADH primarily affects urine output by controlling water reabsorption and does not directly regulate acid-base balance or blood pressure. Therefore, choices A and B are incorrect because ADH does not directly influence acid-base balance or blood pressure.

5. What is the term for the involuntary muscle contractions that move food through the digestive tract?

Correct answer: B

Rationale: Peristalsis is the correct term for the involuntary muscle contractions that move food through the digestive tract. These contractions help push food along the digestive system, facilitating digestion and absorption of nutrients. Segmentation, on the other hand, refers to the mixing and breaking down of food in the intestines, not the movement of food. Chyme is the semi-fluid mass of partially digested food in the stomach and small intestine, not the muscle contractions. Emulsification is the process of breaking down fat globules into smaller droplets to aid in digestion, not the movement of food through the digestive tract. Therefore, peristalsis is the most appropriate term for this function.
