Bood volume and blood pressure can be stimuli for the release of vasopressin, changes in osmolarity serve as the strongest stimulus. a. True
b. False

a. True

Explanation:

Vasopressin is a peptide hormone, synthesized in the hypothalamus, that has a strong effect on the kidney, cardiovascular homeostasis, and on the body generally, especially responding to changes in osmolarity of the blood.

Just like every other hormone, vasopressin is a hormone released on-demand, based on the state of the body, the need, its capability to solve a problem. It has its target organ and function. Changes in osmolarity cause kidneys to reabsorb water into the blood is the strongest stimulus responsible for the release of vasopressin. Vasopressin is also stimulated in response to blood volume and blood pressure.

one would be wind another would be water density

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
