Question

Which of the following statements best describes homeostasis?

• A. Keeping the body in a fixed and in altered state
• B. Dynamic equilibrium
• C. Maintaining a near constant internal environment
• D. Altering the external environment to accommodate its body's need

Answer 1

Answer: (C)

Maintaining a near constant internal environment

Homeostasis is the process by which the body maintains a near constant internal environment. This is not the same as keeping the body in a fixed and unaltered state, for instance when we exercise, it is important that our heart rate increases. All living organisms, whether unicellular or multicellular exhibit homeostasis.

Therefore, the correct answer is option C.
