Answer:
Retina; Cochlea
Explanation:
The retina is to the eye as the cochlea is to the ear.
The retina is a thin light sensitive tissue of the eyes, it lines the inside the back of the eyes. The retina receives light focused by the light and converts the light into neural impulses, and this impulses are further sent to the brain for visual recognition or perception.
The cochlea is a watery fluid found in the inner part of the ear and functions majorly for hearing. The cochlea transfers pressure waves into nerve impulses. The watery fluid moves in response to external vibration from the middle ear, this further convert motion to electrical signals to electrochemical impulses that are further processed by the brain.
