C. It creates separation between the cell and the outside.
D. It changes lipids into usable proteins for the cell.
E. It controls the movement of molecules in and out of the cell.
F. It holds all of the genetic material for the cell.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
