Ur data for diffusion of water across a differentially permeable membrane in response to a sucrose gradient could be graphed with change in weight on the vertical axis rather than total weight. how would you interpret the slope of the curves produced when you do this?

The slopes show that sucrose gradient affects change in weight.

The slopes will be different because higher gradient concentration of sucrose will result in the higher amount of water moved. This means the higher sucrose gradient concentration, the more change in weight of the water.
