What mechanisms does the body use to turn responses on and off to maintain homeostasis? A fight-or-flight mechanisms
B Homeostasis mechanisms
C Input mechanisms
D Feedback mechanisms

D Feedback mechanisms

Explanation:

Not 100% sure but strongly believe option D should be correct, if not then B. Homeostasis mechanisms would be my second bet.

I say D because our body has feedback loops which keep everything in check and they are responsible for turning on or off certain things in our body. You probably have heard of Negative and Positive feedback loops those are what I am referring to as they are the main mechanisms which control the homeostatis thus D is my best bet.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
