Cell Membrane Transport The purposes for these experiments is to be able to understand osmosis and its relationship to tonicity of solutions‚ and the transportation of molecules across cell membranes. It’s also used to understand‚ and how temperature affects diffusion. You also learn how to test for presences of starches and sugars in solutions. In the first exercise I will be testing for diffusion through an artificial membranes. This one has forty five steps to it. I will not go into

Stem Cells: Future of Failure? When does a sperm and egg begin to resemble what we call a fetus? Research has shown that at four weeks‚ the embryo is the size of an seasame seed (New Health Advisor). The cells that make up this sesame seed could be the future of regenerative medicine. Stem cells are the cells made during the process of fertilization. They are the first traces of humans‚ making them basically a blank slate for all types of cells. They can become essentially any type of cell in the
