Question

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 . . .because....

you have to create a Hypothesis

Answer 1

The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.

The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.

Answer 2

If molecules are small enough, then they will diffuse across a semipermeable membrane because they can pass through its tiny openings.
