I would say the lens. The lens focuses light. The pupil allows light to come in, the iris gives color and controls how much light comes in.

Lens focuses light rays on the retina.

Further Explanation:

The eye is the sensory organ of the organism that allows it to see the object.

The eye consist of various part:

1. Sclera-Outer covering of the eyeball is tough and has white layer called as sclera

2. Cornea-The light enters the eye through it. It is the curved layer in front of iris and pupil.

3. Pupil-It controls the amount of light entering into the eye

4. Iris-it surrounds the pupil and regulates the amount of light passing into the eyes.

5. Lens-It sits behind the iris. It focusses light onto the retina.

6. Retina-It comprises of photoreceptors and blood vessel that nourishes the former. The two main types of photoreceptor:  

a. Rods: It is responsible for night vision and are more sensitive to light.

b. Cones: It is responsible for color vision.

The eyeball is basically divided into two regions which are filled by the fluid. The two type of fluid found are

1. Aqueous humor: Is present across the space separating cornea and the lens.

2. Vitreous humor: Is present across the space separating the lens and the retina.

During an experiment, readings for blood pressure in a person’s body were found to be constant. However, when measured by a diff
DENIUS [597]

Answer:

This difference indicates that the results are precise but not accurate .

Explanation:

Precise results are those that are very close to the actual result, but do not achieve exactly the same result. In addition, this difference between the precise results is exactly the same. We have an example of this in the case shown in the figure above, where the blood pressure readings measured by the cuff differ by 15 points for each reading. This case also shows us that the results are not accurate, because this type of result is one that shows a result exactly the same as the real one.
