Question
Chapter 41, Problem 5A
Summary Introduction
Introduction:
Feedback mechanisms are the general mechanisms of nervous or hormonal regulation in animals. Negative feedback is when the response diminishes the original stimulus, whereas positive feedback is when the response enhances the original stimulus.

You are encouraged to do research on the mechanisms that enables the responses for these.arrow_forwardWhich of the following is an example of negative feedback? A. High blood sugar will increase the viscosity of blood plasma (plasma is concentrated). In response, water is drawn into the plasma from surrounding tissues in order to dilute the plasma B. Breathing rate increases during exercise to provide more oxygen to muscle cells. Heart rate also increase to increase the speed at which the oxygen is delivered. C. During digestion cells in the stomach produce HCl to begin breaking down proteins, the HCl then stimulates the release of pepsin, to continue breaking down proteins. D. In the immune system, antibodies produced by B-cells bind to antigens, which activates other B-cells to produce antibodies of the same kind.arrow_forward
