Detailed explanation-1: -Negative feedback loops amplify changes to the set point of a system. Positive feedback loops reverse changes to the set point of a system. Negative feedback loops maintain changes to the set point of a system. Positive feedback loops amplify changes to the set point of a system.

Detailed explanation-2: -Negative feedback occurs when a system’s output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body’s homeostasis.

Detailed explanation-3: -Feedback Loops can enhance or buffer changes that occur in a system. Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable.

Detailed explanation-4: -The hallmark of a negative feedback loop is that it counteracts a change, bringing the value of a parameter-such as temperature or blood sugar-back towards it set point.

Detailed explanation-5: -Negative Feedback. In a negative feedback loop, feedback serves to reduce an excessive response and keep a variable within the normal range. Examples of processes controlled by negative feedback include body temperature regulation and control of blood glucose.
