Question

what type of molecules can pass the membrane easier?
large, polar molecules
large, nonpolar molecules
small, polar molecules
small, nonpolar molecules
rewatch

Explanation:

Cell membranes are composed of a lipid - bilayer. Nonpolar molecules can dissolve in the lipid - bilayer, and smaller molecules have an easier time passing through the membrane's pores and spaces. So small, nonpolar molecules can pass through the membrane more easily.

Answer:

small, nonpolar molecules
