D) do not exist in human systems.

Question

Quizplus · Accepted Answer

Positive feedback control systems accelerate a change, rather than reducing the deviation from set point. This can be seen in processes such as blood clotting, where the initial response triggers a series of amplification steps that lead to a rapid clot formation. While positive feedback loops are less common in human systems than negative feedback loops, they do play important roles in certain physiological processes.
