Which 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.
