Answer 1

Answer:

A ) BECAUSE MEMBRANE is not like skin.

Answer 2

A. It is a thin flap of skin acts as sound receiver.

• A second name for the tympanic membrane is the eardrum. It divides the middle ear from the outer ear. The tympanic membrane vibrates as sound waves enter it. The middle ear's minuscule bones are thus exposed to the vibrations. The vibrating signals are then sent from the middle ear bones to the inner ear. The tympanic membrane is formed of a thin connective tissue membrane that is externally covered by skin and internally by mucosa.
• The eardrum, or tympanic membrane, is a thin membrane found in humans. It divides the external auditory meatus from the tympanic cavity. Sound waves are taken in by the external ear and sent to the tympanic membrane. Then, in reaction to the sound waves, the tympanic membrane begins to vibrate.

Hence, option A is correct.
