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 molecules ability to diffuse across a semipermeable membrane?\ if molecules are small enough, then... because...

Explanation:

The principle of diffusion across a semi - permeable membrane is that smaller molecules can pass through more easily due to the size of the pores in the membrane.

Answer:

If molecules are small enough, then they will be able to diffuse across the semipermeable membrane because the pores in the semipermeable membrane are of a size that allows small molecules to pass through but may block larger ones.
