Answer:
 homeostasis is the state of steady internal physical and chemical conditions maintained by living system.
 Diffusion is an important process for living things; it is how substances move in and out of cells.
Diffusion helps maintain homeostasis by creating specific concentrations of molecules inside the body compared to outside and Cells in homeostasis are successfully maintaining the internal conditions necessary for basic functioning
 The cell needs to export waste and other molecules, and import fuels and fluids. Plasma membranes allow water, oxygen and carbon dioxide to pass through by osmosis, or passive diffusion.
