Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!
Explanation:
Shivering as a natural, involuntary response to generate heat is an example of maintaining homeostasis by regulating body temperature.
Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.
When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.
The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.
