Fill in the blanks below to complete the hypothesis for this lab. It should answer the lab question, "What is the effect of molecule size on a molecule's ability to diffuse across a semipermeable membrane?" If molecules are small enough, then . . .

They can pass through the semi permeable membrane

Explanation:

The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through

If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
