Sound-induced vibrations depolarize hair cells of the cochlea by opening ion channels that are gated in what way

The process where physical  forces are converted into biochemical signals is called mechanotransduction. The outer and inner hair cells in the cochlea detect the vibrations created by the sound waves in the environment. The sensitive ion channels are mechanically activated. It powers the amplification of sounds and supports the relay of the converted electrical signals via auditory nerve to auditory brainstem to auditory cortex.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.

c is the answer. hope this
