Short Answer

Expert verified
The correct answer is (a) androgens; endocrine.

Step by step solution

01

Identify the hormone responsible for facial hair growth

We should first identify the hormone that is responsible for facial hair growth. Estrogens are a class of hormones that are primary female sex hormones. Androgens, on the other hand, are a class of hormones that increase the development of male characteristics. Since facial hair growth is a male characteristic, Androgens are responsible for this development.
02

Identify the system that the hormones affect

Now we need to identify the system that is affected by these hormones to cause the growth of facial hair. The endocrine system is a network of glands that produce and release hormones into the bloodstream, where they can be delivered to organs and tissues. The central nervous system is responsible for controlling the functions of the body and mind. Given that hormones are released into the bloodstream, the endocrine system is the correct choice.
03

Match the information with the given options

Finally, we should match the hormone and system identified in previous steps with the given options. Since we have determined that the hormone responsible for facial hair growth is Androgens, and the system affected by these hormones is the endocrine system, option (a) Androgens; endocrine is the correct answer.
