Answer to Question 1

A
Feedback:
Estrogens are responsible for developing and maintaining the female reproductive organs. Progesterone is the most important hormone for conditioning the endometrium in preparation for implantation of the fertilized ovum. Androgens, secreted by the ovaries in small amounts, are involved in the early development of the follicle and affect the female libido. Follicle-stimulating hormone is responsible for stimulating the ovaries to secrete estrogen.

Answer to Question 2

A
Feedback:
Vitamin B12 cannot be taken orally, because one problem with pernicious anemia is an inability by the patient to absorb vitamin B12 due to low levels of intrinsic factor. Other options are incorrect.
