Final answer:
d) Pinna, tympanic membrane, cochlea. The correct order of structures for sound waves from outer to inner ear is pinna, tympanic membrane, cochlea.
Step-by-step explanation:
The correct order when describing the structures that sound waves travel through as they pass from the outer ear to the inner ear is: d) Pinna, tympanic membrane, cochlea.
First, the sound waves travel through the pinna (outer ear), which collects and focuses the waves. Then, the waves reach the tympanic membrane (eardrum) in the middle ear, causing it to vibrate. Finally, the vibrations are transmitted to the cochlea in the inner ear, which contains sensory receptor cells for hearing.
