Question

1. what is the primary function of the cochlea in the process of hearing?to amplify sound waves from the eardrum.to separate the middle ear from the inner ear.to transmit vibrations from the malleus to the stapes.to convert fluid vibrations into nerve impulses via hair cells.

Explanation:

The cochlea is a structure in the inner ear where fluid vibrations (from middle ear transmission) are converted into nerve impulses via its hair cells, which the brain interprets as sound. The other options describe functions of other ear structures: amplifying sound from the eardrum is a role of middle ear ossicles, separating middle and inner ear is the eardrum/oval window's role, and transmitting vibrations between ossicles is the job of the ossicle chain itself.

Answer:

To convert fluid vibrations into nerve impulses via hair cells.
