What is the purpose of the bones in the middle ear? They protect the cochlea from intense sound.
They send electrical impulses to the brain.
They amplify the motion of the eardrum.
They block unnecessary noise.

Option (C) is Correct.

These are responsible for transferring and amplifying the vibrations from outer ear to inner ear.

Plzz mark me as Brainaliest...

They send electrical impulses to the brain.

Explanation:Inside the middle ear, three small bones (ossicles) form a chain and conduct sound vibrations from the eardrum to the inner ear. Once in the fluid-filled inner ear, sounds are converted into nerve impulses and sent to the brain.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
