Students have asked these similar questions

One strain of bacteria was found to have a membrane potential of -120 mVmV at a pHpH of 7.5. A bacterium can be modeled as a 1.5-μmμm-diameter sphere. How many positive ions are needed on the exterior surface to establish this membrane potential? (There are an equal number of negative ions on the interior surface.) Assume that the membrane properties are the same as those of mammalian cells.

Q: Draw the fabrication layers of a transistor with metal and semiconductor MS junction (Schottkyj unction).
