identify the structure that regulates the amount of light entering the posterior segment of the eye.

Answers

Iris is the structure that regulates the amount of light entering the posterior segment of the eye.

The colored disc-shaped membrane found in the eye of humans and various animals is called the iris.

The pupil appears in the center of the iris: an opening that allows light to enter.

It is located behind the cornea, constituting a separation between the posterior chamber and the anterior chamber of the eye.

It helps to dilate or contract the pupil to allow more or less light to enter the eye.

Therefore, we can conclude that iris is the structure that regulates the amount of light entering the posterior segment of the eye.

B4O HRELP ME IM A FRESHMAN DUDE PLS

Answers

Answer:

Cell

Explanation:

Hi there!

A cell is the smallest unit of a living thing. However, a cell, much like a person, must have other parts inside of it in order to function (it can't function by itself).

The nucleus, ribosomes, and mitochondria are all structures inside of a cell; they are some of the organelles inside of a cell, which help the cell do specific jobs, a bit like how a machine needs special pieces in order to do certain tasks.

Therefore, a cell is the structure that includes all of the others, since the other structures are organelles that help the cell function, and they are all inside of the cell.

Hope this helps!
