Once uniformly distributed (i.e., at equilibrium), the molecules of the substance continue to move about, but the net movement is zero. In the absence of convection currents, the movement of the molecules i

The chamber is completely divided into two compartments by a thin membrane made of celloidin, which has negatively charged pores. A solution of any sal

Most proteins have an acid isoelectric point, so that at a pH near 7.0 they possess a net negative charge. The charge at the outer surface of the

In this chapter, we examine some of the striking changes that occur in the electrical properties of ventricular myocardial cells during embryonic development of chick hearts. The electrical properties at each stage of development not
