The wide, floppy apex of the basilar membrane is maximally displaced by high frequency sound.

a. True

b. False

Answer: False

Explanation:The basilar membrane is located in the cochlea interior. It has variation in the stiffness near to the oval window and turns floppiest near to apex. Basilar membrane is active near the stiff area which is oval window when it is exposed to high frequency and thus has experiences the excitation of cells of the nerves.

Therefore the apex being less stiff is displaced by the low frequency sound in the basilar membrane, so the statement given is false.
