Answer to Question 1

B
Feedback:
Each ovum is contained in a storage site called a follicle. The follicles act as endocrine glands producing the hormones estrogen and progesterone. The primary goal of these hormones is to prepare the body for pregnancy and to maintain the pregnancy until delivery. Although secretion of these hormones develops the body's reproductive system and initiates the change into puberty, these occur to prepare the body for pregnancy, the primary goal of the hormones. Development of facial hair and deepening of the voice is seen in men as a result of testosterone.

Answer to Question 2

A
Feedback:
Increased testosterone levels in boys at puberty results in thickening of the skin, a deeper voice, development of facial hair, and closure of the epiphyses. These previously established effects would be maintained by the androgens, which still remain in the body following surgical castration. Development of a wide flat pelvis and loss of facial hair are associated with estrogen's effects. An older adult male would not grow taller following surgery.
