Answer #1

Homeostasis is generally maintained by a negative feedback loop that includes a stimulus, sensor, control center, and effector.Negative feedback serves to reduce an excessive response and to keep a variable within the normal range. Negative feedback loops control body temperature and the blood glucose level.

In a “positive feedback control system”, the set point and output values are added together by the controller as the feedback is “in-phase” with the input. ... An example of a positive feedback systems could be an electronic amplifier based on an operational amplifier.
