Question

homeostasis is maintained by which of the following?
diffusion of molecules from an area of high concentration to lower
osmosis of water into an area of high solute concentration
active transport of molecules to an area of high concentration
all of the above

Explanation:

Homeostasis is the maintenance of a stable internal environment. Diffusion helps in the movement of molecules to balance concentrations. Osmosis regulates water levels which is crucial for homeostasis. Active transport also plays a role in maintaining proper concentrations of substances. All these processes contribute to maintaining homeostasis.

Answer:

All of the above
