If a star is a brilliant blue color, it's really hot and emits a lot of energy. If it's red, it has a cool surface temperature instead. Therefore, the dominant wavelength of a star's light can tell us its surface temperature.

Answer:
Simple diffusion and Facilitated diffusion
Explanation:
The simple diffusion process involves movement of molecules. This movement occurs from high concentration to low concentration. The facilitated diffusion process is a passive diffusion process. This process requires proteins for movement of molecules, the proteins are carrier and channel proteins.
The enzymes that promote membrane diffusion are carrier proteins. These proteins act as enzymes and allows transport by changing the conformation and opening of channels.
