What is the eventual result of the cellular process of diffusion Describe concentration prior to and at this point?

Description : What is the eventual result of the cellular process of diffusion Describe concentration prior to and at this point?

Last Answer : The eventual result of diffusion is equilibrium.The concentrations prior to this point would be uneven. Thesolutes then diffuse from areas of high solute concentration toareas of low solute concentration. After diffusion, at equilibrium,the concentration will be even in different areas.
