3. Which hormone primarily triggers ovulation in the female menstrual cycle?

Correct answer: C

Rationale: The correct answer is C: Luteinizing hormone (LH). LH is the hormone responsible for triggering ovulation in the female menstrual cycle. During the menstrual cycle, LH surge occurs around day 14, which stimulates the release of a mature egg from the ovary. This surge in LH is crucial for the rupture of the mature follicle and the release of the egg, marking the onset of ovulation. Estrogen and progesterone play important roles in regulating the menstrual cycle, but LH specifically triggers ovulation by signaling the release of the egg from the ovary.

4. Urine travels from the kidneys to the bladder through tubes called:

Correct answer: B

Rationale: The correct answer is B: Ureters. The ureters are the tubes that carry urine from the kidneys to the bladder. The renal arteries and renal veins are blood vessels that supply and drain blood from the kidneys, respectively. The urethra is the tube that carries urine from the bladder out of the body. Understanding the anatomy of the urinary system is important for grasping how waste is processed and eliminated by the body.

6. What is kwashiorkor, a protein deficiency disease, characterized by?

Correct answer: A

Rationale: Rationale: Kwashiorkor is a type of severe acute malnutrition caused by a deficiency of dietary protein. It is characterized by symptoms such as edema (swelling due to fluid retention), skin lesions, an enlarged liver with fatty infiltrates, and muscle wasting. Muscle wasting is a key feature of kwashiorkor due to the body breaking down muscle tissue to obtain essential amino acids for vital functions. Night blindness (option B) is a symptom of vitamin A deficiency, scurvy (option C) is caused by a lack of vitamin C, and rickets (option D) is a condition resulting from a deficiency of vitamin D, calcium, or phosphate.
