Answer to Question 2
Correct Answer: 1
Rationale 1: When testosterone levels rise above normal, the body responds by decreasing the secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary gland. This negative feedback response system triggers a reduction in testosterone secretion from the testes.
Rationale 2: The body does not increase the secretion of estrogen to counteract the effects of the excess testosterone.
Rationale 3: The body does not decrease the release of testosterone directly from the testes.
Rationale 4: Increasing the release of luteinizing hormone and follicle-stimulating hormone does not decrease testosterone secretion.
Global Rationale: When testosterone levels rise above normal, the body responds by decreasing the secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary gland. This negative feedback response system triggers a reduction in testosterone secretion from the testes. The body does not increase the secretion of estrogen to counteract the effects of the excess testosterone or decrease the release of testosterone directly from the testes. Increasing the release of luteinizing hormone and follicle-stimulating hormone does not decrease testosterone secretion.
