Question 2 (2.5 points)
Which of the following is required for the body to function at an optimum level of health?
Highly acidic level
Highly alkaline level
State of homeostasis
None of the answers are correct



Answer :

Final answer:

Homeostasis in the body is crucial for optimal health by regulating internal conditions like pH levels. Buffers help maintain pH balance, and homeostasis ensures stability in biological conditions.


Explanation:

Homeostasis is essential for the body to function at an optimum level of health. It involves maintaining internal conditions within a narrow range despite external changes. For example, the body regulates pH levels to keep cells functioning properly, requiring a slightly alkaline pH between 7.35 and 7.45.

Cells depend on homeostatic regulation of acid-base balance for optimal living conditions. Buffers play a crucial role in neutralizing acids or bases in body fluids to maintain pH balance close to 7.4. Extreme pH levels in either direction are usually inhospitable to life.

Steady state or homeostasis ensures equilibrium in biological conditions for optimal functioning, such as body temperature regulation and maintenance of stable internal factors at constant levels.
