Final answer:
Positive feedback loops create amplification, while negative feedback loops create damping in the effect.
Step-by-step explanation:
Positive feedback loops create an amplification in the effect, meaning that the response becomes stronger and more intense. Examples of positive feedback in biology include blood clotting and childbirth. Negative feedback loops, on the other hand, create a damping in the effect, meaning that the response counteracts and reduces the initial stimulus to restore equilibrium. An example of negative feedback in biology is the regulation of body temperature.
