Answer 1

When the blood becomes overhydrated (hypotonic), the body attempts to maintain homeostasis by regulating the amount of water retained. In this situation, the correct response is:

a. The hypothalamus sends impulses to secrete less ADH.

This occurs because the body recognizes that there is excess water in the blood and reduces the secretion of Antidiuretic Hormone (ADH), leading to less water reabsorption in the kidneys and more water being excreted in the urine.
