Why do bats use echolocation? to detect prey before it detects the bat

to locate safe places to sleep

to hunt for food at night

to defend against predators

Bats use echolocation to navigate and find food in the dark. To echolocate, bats send out sound waves from the mouth or nose. When the sound waves hit an object they produce echoes. Echolocation allows bats to find insects the size of mosquitoes, which many bats like to eat

So i'd say to hunt for food at night. <3

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.
