1. Explain how bats determine the distance (range) of their target using echolocation. Be sure to describe the properties of their call that make it possible (use a sketch), and how these signals are processed by the ear and brain ( use a sketch) in a way that enables them to precisely measure the target distance. How do they hear the echo effectively when the call is much louder? ( use a sketch). Explain this on the physiological level referencing specific structures and specific mechanisms. Use diagrams as need ( a picture is sometimes worth 1000 words)
