2. cochlea changes shapes to help you focus
3. retina changes light rays into neural impulses
4. lens stimulates the neurons in your olfactory epithelium
5. odor molecules location where sound waves strike

Answer 1

1. Eardrum: location where sound waves strike

2. Cochlea: contains receptors for hearing

3. Retina: changes light rays into neural impulses

4. Lens: changes shape to help you focus

5. Odor Molecules: stimulates the neurons in your olfactory epithelium

Answer 2

1. ear drum contains receptors for hearing.

Step-by-step explanation:

Ear drum is an important part of human ear. Its function is to change the sound waves into vibration form and send these vibrations to the inner ear through middle ear i. e. cochlea which is responsible for the hearing and recognizing different sound. Cochlea is a main organ of ear for hearing sounds. If cochlea is damaged, sound can't be hear.
