Allan Townsend · Answer 1

The amount of water in the beakers

Explanation:

The Cell Homeostasis Virtual Lab is an online experiment that illustrates the principles of homeostasis, osmosis and diffusion. The materials consist of beakers, dialysis tubing, sugar and water. The experiment measures the change in the mass of a solution at varying concentrations of sugar. The experiment demonstrates diffusion of sugar molecules through the dialysis tubing into the water-sugar solution. The change in the sugar concentration is the independent variable as it changes and in turn effects the dependent variable. The response or dependent variable, in this experiment, is the mass of the solution. The amount of water in the beakers does not change. Therefore, in this experiment, it is a constant value.
