Homework Help: Biology

In each set up the dialysis tubing contains a solution of 30% glucose and safranin. However, the set ups differ in the contents of the beaker. The control set up has the same solution in the beaker while in the experimental set up it contains just water. In both the level of fluid in the pipette is drawn half way up the pipette so that any change of volume of the dialysis tubing can be accurately measured. The dialysis tubing is permeable to water, glucose and the dye.

1. What is the relative osmotic concentration of the contents of the dialysis tubing with respect to the distilled water? (isotonic, hypotonic, hypertonic)

2. in which direction will osmosis occur? why?

thanks!
