Hair cells in the cochlea connect with fibers from the auditory nerve to perform what action? a. they convert auditory stimuli into neural signals the brain can process. b. they carry neural signals about a sound wave’s frequency to the brain. c. they transmit sound vibrations from the eardrum to the inner ear. d. they transfer sound vibrations from the eardrum to the auditory cortex.

The right option is; B.  They carry neural signals about a sound wave’s frequency to the brain.

The cochlea is the sense organ that converts sound into neural signals that is sent to the brain. The cochlea contains hair cells that are responsible for hearing. The lower part of the hair cells are joined to the basilar membrane. Within the cochlea, sound waves make the basilar membrane to vibrate up and down and to generate nerve impulses. Below the hair cells are the auditory nerve fibers which pass the signals about a sound wave’s frequency to the brain.

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
