Answer 1

Secondary sexual characteristics may develop in response to testosterone and estrogen. Testosterone is responsible for the development of secondary sexual characteristics in males, while estrogen is responsible for the development of secondary sexual characteristics in females.

Step-by-step explanation:

Secondary sexual characteristics may develop in response to testosterone and estrogen. Testosterone is responsible for the development of secondary sexual characteristics in males, such as deepening of the voice, growth of facial hair, and the development of the sex drive. Estrogen, on the other hand, is responsible for the development of secondary sexual characteristics in females, such as the growth of breasts and widening of hips.
