Question 1

Give an example of how bats use biosonar to determine the size and distance of targets.

Accepted Answer

Student examples will vary.A sample answer follows.A bat gives out a call that hits a mosquito about five feet away.Because a mosquito is a small creature, it returns small echo.However, because the mosquito is fairly close, this echo comes back quickly.By recognizing the quickness of the echo's return and its size, the bat realizes that a mosquito is about five feet away.
