Final answer:
Homeostatic mechanisms are regulated by negative feedback loops.
Step-by-step explanation:
Homeostatic mechanisms are regulated by negative feedback loops. These feedback loops involve a stimulus, sensor, control center, and effector. The sensor senses the value of the variable and sends data to the control center. The control center compares the actual value with the normal range and sends signals to the effector, which works to move the variable back within the normal range.
