1. A dialysis bag filled with 0,2% glucose is placed into a beaker containing 10% glucose. The dialysis bag has a pore size that will allow the passage of water, but not glucose molecules. At the start of the experiment,
1. Which way will water move, into or out of the dialysis bag, and
2. Describe the tonicities of the water in the bag and in the beaker at the start of the experiment.
2. Two beakers are set up with a connecting tube that contains a semipermeable membrane that will allow water molecules to pass through, and will also allow fructose molecules to pass through. At the start of the experiment, the left beaker contains 10% fructose, and the right beaker contains 0.5% fructose. At the start of the experiment, 1) which way will water move 2) which way will fructose move and 3) which beaker is hypotonic and which is hypertonic?
3. Sheep red blood cells are added to a beaker containing a solution of 0.2% NaCl. What will happen to the cells? Describe the tonicities of the cells and the solution in the beaker?
