When the echolocation sound bounces off of an object and returns to the dolphin/whale, the sound waves are picked up by fat around the lower jaw and ear which are then transmitted by the ear to the brain. O True O False

Some types of antibiotics can permanently destroy hair cells near the base of the cochlea, close to the oval window. What kind of hearing loss would we expect if this happens? O the selective loss of hearing high pitched sounds O less tolerance for loud sounds O less ability to hear soft sounds O the selective loss of hearing low pitched sounds

In order for an animal to be detected by echolocation the animal must _____. be the same density as the surrounding medium be larger than the wavelength of sound used be smaller than the wavelength of sound used  be able to produce sounds at frequency that is similar to the frequency being used to locate it

How do the size and shape of the outer ear help animals detect sounds and localize sounds? Since the outer earis an amplifier, animals with an acute sense ofhearng often have large ears.
