Cells transport molecules into the cell in many different ways. one method is through endocytosis, shown in the model. in endocytosis, the cell brings specific molecules it needs, including fluid, into the cell. why does the structure of the plasma membrane make this type of transport necessary for fluids?

That would be a working theory.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.

Wheres the rest of the answers to the question?
