To describe:
The term “positive feedback”. Also, determine whether it is always harmful and how often does it occur naturally.
Concept introduction:
There are two types of feedback mechanisms in the body. One is positive feedback and the other is negative feedback. Both these feedback mechanisms are exactly opposite to each other and are useful for the body.
To determine:
Whether positive feedback is always harmful.
