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.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

d. organisms have cells with different shapes and functions.
