Answer: diffusion
Step-by-step explanation:
Osmosis is defined as the process in which molecules of a solvent tend to move through a semipermeable membrane from a region of low concentration solution to a region of more concentrated solution in a membrane.
Solution is the homogeneous mixture of solute and solvent where solute is the component which is present in smaller proportion and solvent is the component which is present in larger proportion.
Diffusion is defined as the random motion of molecules from areas of higher concentration to lower concentration.
Homeostasis is the active regulation and maintenance of a stable internal physiological state in the face of a changing external environment.
