outward across the cell membraneinward across the cell membranetangentially to the cell membraneCorrect Solution The cell membrane is composed of a bilayer membrane that is non polar on both outer surfaces and polar in the center, so my answer is B, inward across the cell membrane. E = V/d = 7.4 * 1 0^(-2) / (0.1 * 10 ^(-6)) = 74 * 10^4 V/m = 740 v/km.

Solution
The cell membrane is composed of a bilayer membrane that is non polar on both
outer surfaces and polar in the center, so my answer is B, inward across the cell membrane. E =
V/d = 7.4 * 1 0^(-2) / (0.1 * 10 ^(-6)) = 74 * 10^4 V/m = 740 v/km
