Question

which phrase best defines homeostasis?
the maintenance of an organisms internal environment within certain limits
the maintenance of an organisms external environment within broad limits
the ability of an organism to find a mate
the ability of an organism to find its own food

Explanation:

Homeostasis is the process by which organisms maintain a stable internal environment despite external changes. It involves regulating factors like temperature, pH, and nutrient levels within a narrow range. Options about external environment (not relevant as homeostasis is internal), finding a mate (reproduction - unrelated), and finding food (nutrition - not the core of homeostasis) can be eliminated.

Answer:

the maintenance of an organism's internal environment within certain limits
