Solutions

Expert Solution

​1. D. Neighbouring solutions that have unequal concentrations of molecules. Despite the fact the solutions are separated by a membrane, details thereof of the nature if the membrane in transporting the molecules across the to help in homogenising the solution is not mentioned clearly. So abstractly stating the answer will be D.

​2. A. Simulate biological membranes. This acts as semipermeable membrane helping in diffusion and osmosis processes using a visking tube where the kidney patients blood could be purified like mimicking the function of kidney.

The membrane of a living cell is an insulator that separates two conducting fluids. Thus, it functions as a capacitor. The membrane is not a perfect insulator, however. It has a small conductance, making it a leaky capacitor. In this problem, you will estimate the RC time constant of the cell membrane. (a) A cell membrane typically has a capacitance per unit area on the order of 1 μF/cm2 — i.e., 1 cm2 of the membrane material would have a...
