Ms. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set- up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions: a. No solute will exhibit a net diffusion out of the cell. b. Glucose will exhibit a net diffusion into the cell. c. NaCl will exhibit a zero net movement. d.
