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.

answer; /// i believe that the correct answer is (50%);

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
