1. Why is it necessary to have positive and negative controls in this experiment?
It is necessary to have positive and negative controls in this experiment to see how variables are affected; therefore, without controls there would be no way to now what would normally happen with the chemical reactants.
2. Describe the movement of each substance in the dialysis bag and the beaker.
The movement of glucose in the dialysis bag was that is crossed the dialysis membrane; therefore, it was found in the beaker solution. The starch solution on the other hand remained in the dialysis bag and was not found in the beaker.
3. Which substance(s) crossed the dialysis membrane? Support your response with data-based evidence.
Glucose was the
