Sweating to regulate body temperature is an example of
A
negative feedback
B
positive feedback
C
a homeostatic imbalance
D
aging
Explanation: 

Detailed explanation-1: -If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level. Once the body temperature is back to the correct level, sweating will stop.

Detailed explanation-2: -High body temperature may stimulate the temperature regulatory center of the brain to activate the sweat glands to bring the body temperature down. When body temperature reaches normal range, it acts as negative feedback to stop the process. Feedback may be negative or positive.

Detailed explanation-3: -A typical example of a negative feedback mechanism in the human body is the regulation of body temperature via endotherms. When the body’s temperature rises above normal, the brain sends signals to various organs, including the skin, to release heat in the form of sweat.
