Final answer:
Positive feedback sets off more changes in the same direction and leads to amplification and a move away from equilibrium, while negative feedback performs a corrective action in the opposite direction of the stimulus to maintain stability and equilibrium.
Step-by-step explanation:
Positive feedback is the type of feedback where a change in a variable sets off more changes in the same direction. It leads to an amplification of the effect and a move away from equilibrium. An example of positive feedback is the process of blood clotting, where the clotting factors activate more clotting factors, leading to a rapid clot formation.
On the other hand, negative feedback is the type of feedback that performs a corrective action in the opposite direction of the stimulus. It aims to maintain stability and equilibrium. An example of negative feedback is the regulation of body temperature. When the body temperature is too high, the hypothalamus signals the sweat glands to produce sweat, which cools down the body.
