(6 of 10) the plasma membrane is normally permeable to which of the following? ○ gases ○ ions ○ large, uncharged polar molecules ○ two of these are correct ○ none of these are correct note: clicking any button other than the save answer button will not save any changes to your answers!

Explanation:

The plasma membrane is selectively permeable. Gases like oxygen and carbon dioxide can pass through the lipid bilayer via simple diffusion because they are small, non - polar molecules. Ions are charged and cannot pass through the non - polar lipid bilayer easily without specific channels. Large, uncharged polar molecules also have difficulty passing through the lipid bilayer. So the plasma membrane is normally permeable to gases.

Answer:

Gases
