Please answer these questionsin a brief but detailed manner. (Picture is for the 3rd question) 1. is the surface area of every object always gonna be uniform? Will it always be able to distribute the charges equally so that every positive matches up with a negative one?2. I am having trouble understanding by what they mean by potential drop and its relationship to capacitance, could anyone explain this to me?3. Could this be defined as polarizability because it has a dipole moment in a sense? Although it doesn't describe a charge within the egg membrane it was described that the membrane would allow positive ions to flow into the inside making the outer charge change significantly.

polyspermy. The cell membrane of the unfertilized egg has a potential difference of about 70 mV across it, with the inside of the egg negative with respect to the seawater. Since the membrane is quite thin, the electric eld within the membrane is very high. When the first sperm enters the egg, ion channels in the egg membrane open to allow 4.1 a.+ to enter, rapidly reversing the po tential inside the membrane to pos itive. A sperm can fuse with the egg only when the membrane's electric eld is in the original orientation, so a second sperm trying to pene- trate the egg is blocked. If an exper' imenter reverses the direction of the electric field, no fertilization takes place
