Explanation:

What happens to the protein of the cell membrane that surrounds a large molecule during endocytosis?
jarptica [38.1K]

When we say endocytosis, this is one of the cellular processes wherein the cell absorbs substances from the outside by invaginating the cell membrane.

The answer would be it separates from the membrane

The pupil is attached to the ciliary muscles which dilate and contracts in the response of the intensity of light as during high light intensity, the pupil constricts whereas during the low light intensity the pupil dilates to allow the maximum amount of light.

Thus, pupil and retina is the correct answer.
