Question

as an individual approaches puberty, which is the first change to occur?
a.) an increase of sensitivity in the hypothalamus and pituitary to positive feedback
b.) a decrease of sensitivity in the hypothalamus and pituitary to negative feedback
c.) a decrease of sensitivity in the hypothalamus and pituitary to positive feedback
d.) an increase of sensitivity in the hypothalamus and pituitary to negative feedback

Explanation:

As an individual approaches puberty, the first change that occurs is a decrease of sensitivity in the hypothalamus and pituitary to negative feedback. This allows the release of gonadotropin - releasing hormone (GnRH), luteinizing hormone (LH), and follicle - stimulating hormone (FSH), which are crucial for the development of secondary sexual characteristics.

Answer:

B. A decrease of sensitivity in the hypothalamus and pituitary to negative feedback
