Passive Transport Practice

When you inhale, oxygen, a small non-polar gas moves into your lungs and when you exhale, carbon dioxide, a small non-polar gas moves out of your lungs.

________ is the process of moving small and non-polar molecules directly across the cell membrane from high to low concentrations.
