scientific problems

1, bat's eyes are useless when avoiding obstacles. Because after blindfolding, the percentage of bats avoiding obstacles increased slightly.

Bat's ears play an important role in avoiding obstacles. Because the bat's ears are covered, the percentage of bats avoiding obstacles has dropped a lot.

Bat's ears play an important role in avoiding obstacles. Because covering one ear is the same as covering two ears, bats avoid obstacles in the same proportion. This is like two eyes of a person, and the position is determined by the intersection of the light obtained by the two eyes.

Bat's mouth plays an important role in avoiding obstacles. Because after being silenced, the percentage of bats avoiding obstacles has dropped a lot.

5. The bat sends out ultrasonic waves with its mouth, and the ultrasonic waves reflect back to reach the bat's ears respectively, and the bat pushes back accordingly to determine the position and size of the obstacle, thus identifying the object.
