If your body is dehydrated,having insufficient fluid levels in the blood,the control center in the brain will stimulate the release of a hormone which will cause water to be reabsorbed into the blood during urine formation.When the control center senses that enough water is reabsorbed,it will stop the release of the hormone.This is an example of
A) a negative feedback mechanism.
B) a positive feedback mechanism.
C) response to external stimuli.
D) lack of control over homeostasis.
E) a combination of negative and positive feedback.

This is an example of a negative feedback mechanism because the control center works to reverse the deviation from the set point (insufficient fluid levels in the blood) by initiating a response that returns the body to homeostasis (reabsorbing water into the blood), and once the set point is reached, the stimulatory signal is reduced (stopping the release of the hormone).
