How is sound detected by the brain? a. bones amplifying sound b. electrical impulses from the ear c. electromagnetic waves d. vibrations quick!

Sound waves enter the ear and cause the eardrum to vibrate. These vibrations pass through connected bones in your ear. This makes fluid move in the inner ear. The impulses of the fluid is converted in the brain to what we "hear".

D

what was the answer?

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
