Question

Quizplus · Accepted Answer

Most homeostatic mechanisms operate on the principle of negative feedback, where a change in a variable triggers a response that counteracts the initial change and returns the variable back to its optimal range. Positive feedback mechanisms, on the other hand, amplify a change and push the variable further away from its optimal range. Positive feedback mechanisms are rare in homeostasis and tend to be involved in processes such as blood clotting, childbirth, and the menstrual cycle.
