Which 3 of the following are examples of feedback mechanisms which maintain homeostasis? a. antibodies binding to a virus b. flagellate rotation for a cell movement c. insulin secretion in response to high blood sugar d. increased heart rate in response to exercise e. protein synthesis f. proton pumping to maintain a proper ph level

The correct answer is-

C. Insulin secretion in response to high blood sugar.

D. Increased heart rate in response to exercise.

F. Proton pumping to maintain a proper pH level.

Homeostasis can be described as a tendency of living organisms to maintain a state of stable internal environment. In other words, it is the tendency to resist any change in the optimal conditions for survival.

It is brought by several regulatory mechanisms in the body such as regulation of body temperature, regulation of pH, regulation of osmolarity etc.

Thus, option C), D), and F) are the examples of feedback mechanisms  that help in maintaining homeostasis.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
