Dilation and constriction of the pupil are controlled by the

Explanation:

Iris is the part of the eye which is involved in controlling of the working mechanism of the pupil. It is a thin membrane which surrounds pupil. The specialized muscle present in Iris region of the eye are involved in controlling of light entry and its effect on the pupil.

When the light entering the eyes are very bright, it makes the iris to constrict and which in turn causes the pupil to constrict, whereas when the light entering the eyes is very dim, the iris dilates and causes pupil to dilate.

answer:

sequence 1- deletion

                  2- duplication

                  4- substitute

                  5- inversion

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
