peer agreement (net): +4feedback mechanism Explanation: That's common in biological fields. Please see following for ref.: Feedback mechanism Definition noun (1) A loop system in which the system responds to perturbation either in the same direction (positive feedback) or in the opposite direction (negative feedback). (2) A process in which the level of one substance influences the level of another substance. (3) A mechanism or a signal that tends to initiate (or accelerate) or to inhibit (or slow down) a process. Supplement An example of positive feedback loop is the onset of contractions in childbirth. When contraction begins, the hormone oxytocin is released into the body to stimulate further contractions. As for the negative feedback loop, an example is the regulation of blood glucose levels. If blood glucose levels continue to rise it may result in diabetes. In fact, there are many biologic processes that use negative feedback to maintain homeostasis or dynamic equilibrium. http://www.biology-online.org/dictionary/Feedback_mechanism |
