Answer 1

Answer 7. Correct options are-

C) moving fluids along the reproductive tract

D) buffer production

These are correct because the fluids are from seminal vesicle and prostate, and buffer is also produced by prostate, both of which are accessory reproductive glands.

A), B) and E) are wrong because these functions are regulated by testes, which is a primary sex organ.

Answer 8. A) low sperm cell production

B) increased level of GnRH in the blood

D) a lack of growth plate ossification

E) lower energy levels in the body

Reason- Interstitial cells produce testosterone which stimulates spermatogenesis. Thus low level of testosterone results in low sperm cell production and as a result of positive feedback, levels of GnRH in the bool rises.

Answer 9. B) decreased level of GnRH.

This is because due to negative feedback, increased levels of testosterone cause the hypothalamus and anterior pituitary to release less GnRH, FSH and LH.

Answer 10. A) sterility

Reason- Vasectomy results only in sterility of the individual; there's no decrease in ejaculation as it comes from seminal vesicles, which are not blocked. Muscle mass, and erection capabilities are regulated by testosterone, on whivh vasectomy has no effect at all, as the testes aren't removed, only the sperms redirected.

The production of testosterone hormone is, again, unaffected.
