Describe three forms of passive transport

Diffusion - The movement of molecules from a region of higher concentration to a region of lower concentration.

Facilitated diffusion - This process does not require ATP but does require cell membrane proteins which are called carrier proteins to carry the molecules across the cell membrane from an area of higher concentration to an area of lower concentration

Osmosis - is the movement of water through a semipermeable membrane to a higher concentration of solutes.

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.
