Question

this arrangement prevents certain molecules from crossing the lipid bilayer o phospholipids are tightly packed, which means large molecules cannot fit bet small nonpolar molecules can cross, but ions and most polar molecules cann they are repelled by the nonpolar fatty acid tails. some very small polar mole are able to pass through, but they do so at a slow rate. which of the following molecules can pass through the lipid bilayer without as all that apply. oxygen, a small nonpolar molecule glucose, a large polar molecule sodium ion, a charged molecule water, a very small polar molecule

Explanation:

The text states small non - polar molecules can cross the lipid bilayer without assistance. Oxygen is a small nonpolar molecule, while glucose (large polar), sodium ion (charged), and water (polar) have difficulty crossing without help.

Answer:

oxygen, a small nonpolar molecule
