AP BIOLOGY

Detailed explanation-1: -High pitched sounds are convenient because they can be tailored to be unnoticed by the prey the animals are hunting. Bouncing signals off submerged outcrops or cave walls allows them to swim or fly swiftly through tight surroundings.

Detailed explanation-2: -Dolphins and whales use echolocation by bouncing high-pitched clicking sounds off underwater objects, similar to shouting and listening for echoes. The sounds are made by squeezing air through nasal passages near the blowhole.

Detailed explanation-3: -These links might arise through experience; smaller animals such as mice and birds typically make higher-pitched sounds, whereas large animals like bears vocalize at a lower pitch.

Detailed explanation-4: -Pitch. The sound an object makes changes depending on how fast it is vibrating. When an object vibrates quickly, high-pitched sounds are heard. Low-pitched sounds come from things that vibrate more slowly.

Detailed explanation-5: -Bats produce echolocation by emitting high frequency sound pulses through their mouth or nose and listening to the echo. With this echo, the bat can determine the size, shape and texture of objects in its environment.
