Problem:

The most common feedback loops in the body use the principle of negative feedback. But in some cases, positive feedback occurs for a limited amount of time. One example of this is in the formation of certain clotting factors when blood clotting is initiated. In this scenario the body needs a large number of clotting factors created in a short amount of time.

Required:

Question 1: How would a positive feedback loop differ from a negative feedback loop in terms of functional components and responses?

Question 2: Does a homeostatic feedback loop only function when there is a change from the set point? Explain.

Please read all the questions carefully and answer them.
