1.Examine the plot below. How well does it match the data you recorded in table 2? 2.Which dye traveled the fastest? 3.Does the rate of diffusion correspond with molecular weight of the dye? 1.Why is it necessary to have positive and negative controls in this experiment? 2. Draw a diagram of the experiment set-up. Use arrows to depict the movement of each substance in the dialysis bag procedure.

Why or why not?
1. For each of the tubing pieces, identify whether the solution inside was hypotonic, hypertonic or isotonic in comparison to the beaker solution it was placed in. - 30%; hypertonic compared to hypotonic, 15%; hypertonic compared to hypotonic, 3%; isotonic compared to isotonic and 3%; hypotonic compared to hypertonic solution. 2.Which tubing increased the most in volume? Why?
