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 d. No net movement of lactose from the inside to outside of the cell.
Make sure to label properly the substance inside the beaker and inside the DM bag.
