What is a main function of fats in the body?

The human body needs a certain amount of fat to function. This is because fats in the body not only store important nutrients, but since they cannot produce their own, they act as messengers helping proteins do their jobs. Additionally, fats help insulate a person's body to protect them from drastic temperature changes.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
