Imagine a cell with a plasma membrane permeable to K+ but not Cl-. At the start of the experiment there is 10 milliMolar (mM) KCl outside and 100 mM KCl inside. Explain your answers. a. At equilibrium will the concentration of K+ be equal on both sides of the membrane? b. At equilibrium will the bulk solution on the outside have a net negative charge? c. At equilibrium, will the inside surface of the plasma membrane be positive or negative?

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
