Problem: What is the missing first step of the following process: - The bat makes sounds with their mouth or nose - The sound waves travel away from the bat - The sound waves hit objects - The sound waves bounce off the objects back towards the bat - The bat hears the sound waves echoing off the objects - The bat knows where the objects are because of where the sound echoed from - The bat doesn't hurt itself by hitting the objects.
