Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
There are two tidal bulges on the opposite sides of our planet Earth. It is because of the gravitational force of the moon and the inertias counterbalance.

And together, they are the ones who are responsible for creating two major tidal bulges on our Earth.
