Which of the following is not true about an animal that damages it eyes?

• If the animal is a predator, it might have a more difficult time hunting with worse vision.

• The animal might rely more on its senses of smell and hearing to make up for its lost vision.

• An animal that loses some or all of its vision will not have any disadvantages surviving compared to a healthy animal.

• If the animal is a prey animal, it could be prevented from seeing when a predator is approaching

Which structure is at the back of the human eye where light through the lens is focused?

• ​rod

• ​retina

• ​cornea

• ​pupil

A ________  lens is thinner in the middle and always makes objects look smaller.

• concave

• convex

• translucent

• opaque

Which of the following is not true about how animals see objects?

• ​Visible light reflects off of an object and passes through the cornea and pupil on the way to the back of the eye.

• Some animals have different structural adaptations that allow them to see differently.

• ​Some animals eyes allow more light in so that an animal can see better in low light.

• ​Some animals have eyes that allow them to see when no visible light is present without the help of other detection systems.
