While you are waiting (20 minutes), complete the following exercise: (a) List the initial locations (inside or outside the bag) of all of the molecules that are available for osmosis through the membrane, and then LABEL them in the picture below: (b) For each molecule you listed in (a), PREDICT their direction of net (overall) diffusion: into the bag, out of the bag, both into and out of the bag equally, or none (will not diffuse across the membrane). State your reason for each prediction.
