Question

Cells can function____ A. in rapidly changing temperatures and pHs. B. in a wide range of pHs and temperatures. C. only in a narrow range of temperature and pH. D. at any temperature and pH.

Answer 1

Correct answer: C) Only in a narrow range of temperature and pH

Homeostasis is defined as the ability of the body to regulate temperature and internal conditions even when there is a change in the external environment. Homeostasis is important for the survival of life because the cells of all the organism can function well only in a limited range of temperature and pH.

All the cells of the body use enzymes for proper function, and the enzymes can only function under a limited range of temperature and pH. In extreme conditions of cold or heat enzymes will not be able to function properly and lead to the death of the cell.
