Final answer:
A positive feedback loop amplifies deviations from a set point, pushing an organism's physiology further away from its normal conditions, and is the opposite of the more common negative feedback loop.
Step-by-step explanation:
The type of feedback loop that pushes an organism's physiology further away from its normal setpoints is known as a positive feedback loop. Unlike negative feedback loops, which aim to maintain homeostasis by correcting deviations from a set point, positive feedback mechanisms actually amplify those deviations. A classic example of a positive feedback loop in biology is the process of blood clotting, where an initial clot attracts more platelets, leading to a rapid accumulation and a larger clot to stem bleeding.
