Answer:
<em>The cochlea</em> is the structure which receives information from the hair cells of the inner ear and conveys that information to the brain's auditory system.
Explanation:
The cochlea can be described as a snail-shaped structure which is present in the inner ear. The main function of the cochlea is to receive sound information in the form of vibrations and convert these vibrations into nerve impulses so that our brain can help us to interpret the particular type of sound. The cochlea is hence known to be the auditory part of the inner ear due to its important function.

Answer:
The correct answer is: Pupil.
Explanation:
- Light enters inside the side through a small opening in the iris of the eye which is called the Pupil.
- The outer most part of the eye Cornea and the outer chamber aqueous humor are both transparent and allow light to refract through them.
- The Iris, which a circular and thin comes next to the cornea and aqueous humor. It is reponsible for regulating the amount of light that can reach the retina by altering the pupil size.
- The change in the size of the pupil is mediated by muscles in the iris.
- There are two types of muscles, radial muscles and circular muscles.
- In bright light, the radial muscles of the iris relax while the circular muscles contract. This decreases the pupil size allowing less light to pass into the retina.
- In dim light, radial muscles of the iris contract while the circular muscles relax. This increases the pupil size allowing more light to pass into the retina.
