Compare and contrast the operation of negative and positive feedback mechanisms in maintaining homeostasis. And, also provide two examples of variables controlled by negative feedback mechanisms and one example of a process regulated by a positive feedback mechanism. Introduction: A positive feedback mechanism results in a self-amplifying cycle, whereas a negative feedback mechanism identifies a change in the body and activates the mechanism to reverse it.
