Summary Introduction
To review:
The comparison between negative feedback and positive feedback.
Introduction:
The response, which affects the continuity of a system activity, is known as feedback. There are two types of feed as evident in the biological systems. One is positive feedback and another is negative feedback. Negative feedback has a great impact on the biological system. While, a negative feedback is involved in maintaining a process, in which every self-regulated system has all the conditions that help to continue its activity at an optimal level. The process is known as homeostasis.
