The picture shows the inside of an eye.

Which would be found in structure A?

A. retina and optic nerve
B. rods and cones
C. Iris and pupil
D. lens and cornea

Hello, Your answer is D) Lens and Corena

Explanation:

Because the lens goes direct to the light rays and it helps them to focus on light sensitive, and the corena act on a outermost when light strike the corena helps bends or "Refracts" into the income light onto the lens. The only problem it's not "Retina and optic nerve" because the Retina and optic nerve goes to connects the eyes to the brain. And it not B. because the and "Rods and Cone" are responsible for vision at the "Low lights Levels". Maybe it could be C. But the only problem is the "iris and the pupil" are at the ring shape that surrounds at the opening area. So your best answer will be D Lens and Corena. Have a Great day!

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
