Question
Chapter 1, Problem 21CP
Summary Introduction
To explain:
In what way the positive feedback is helpful in blood clotting but not in thermoregulation of the body.
Introduction:
The homeostasis is maintained by the various feedback mechanisms in the body of an individual. The feedback system comprises of both the negative and positive feedback mechanisms that all provide stability to the body of the organism.
