Many disease-causing pathogens, including viruses, rely on the 5 points
ability to gain entry to a cell's interior. Which of the following membrane
components described in the fluid mosiac model most likely play a crucial
role in cell-to-cell recognition?

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.
