The correct answer is A. Homeostasis allows organisms to regulate their temperature.
Explanation:
Homeostasis is a natural process in cells and complex organisms that make these preserve inner stability or equilibrium despite external changes. This includes the ability of organisms to keep adequate hydration levels, temperature, and nutrient levels that are necessary to survive. In the case of temperature, this is part of homeostasis as most organisms have different mechanisms to regulate temperature; for example in the case of humans, when the external temperature increases the body uses sweating as a mechanism to avoid the internal temperature to increase. Thus, one of the reasons homeostasis is important to the survival of organisms is that it allows them to regulate temperature (Option A).
