osmosis

Introduction Osmosis is the diffusion of water across a selectively permeable membrane in living organisms from a hypotonic to a hypertonic solution. (Raven & Johnson, 2000) The speed of which one substance diffuses from one area to another is based upon the free-energy gradient between the two areas. For example, if two substances differ greatly between their areas, it allows the gradient between them to be steep which results in rapid diffusion. If, however, the gradient between …showed first 75 words of 816 total…

Along with our groups’ results, the class average was found out to be the same in their ending results. ------------------------------------------------------------------------ **Bibliography** 1.
