Question

Give examples of;

•A negative feedback control mechanism

•A positive feedback control mechanism

Answer 1

Negative Feedback. Negative feedback occurs when a system's output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body's homeostasis.

In a positive feedback mechanism, the output of the system stimulates the system in such a way as to further increase the output. ... The feedback increases the strength and frequency of the contractions until the baby is born. After birth, the stretching stops and the loop is interrupted.
