What is the function of a pupil?

• To let light into an animal's eye.

• To send information to the brain.

What is the correct order that light/information travels to the brain?

• optic nerve - pupil - brain - light receptors

• light receptors - pupil - brain - optic nerve

• brain - optic nerve - pupil - light receptors

• pupil - light receptors - optic nerve - brain

A science class is studying light. A student in the class claims that light is not necessary for the eyes to see objects, since some people can see in the dark. Why is this student’s claim inaccurate?

• Light is not necessary to see objects and when it is dark outside.

• The eyes work with other parts of the brain to see objects when there is no light outside.

• Even the smallest amount of light that is outside at night reflects off the surface of an object,

  and then the eyes can see the object.

• The eyes convert light into an object that can be seen against shadows.

What does the arrow in Step B represent?

• reflected light from the sun shining on the bush

• reflected light from the animal’s eyes traveling to the bush

• reflected light from the bush shining on the moon

• reflected light from the bush traveling to the animal’s eyes

Scientists are studying two different animals. One animal hunts for prey at night, while the other hunts for prey during the day. Which of the following claims about how they see light is most accurate?

• The night hunter has low sensitivity light receptors while the day hunter has high sensitivity

  receptors.

• The night hunter and the day hunter both have low sensitivity light receptors.

• The night hunter and the day hunter both have high sensitivity light receptors.

• The night hunter has high sensitivity light receptors while the day hunter has low sensitivity

  receptors.

A student wants to develop a model that shows how the eyes see objects. He creates three possible models.

Which model best demonstrates the concept?

• Model 1

• Model 2

• Model 3

• All models are accurate.

You want to choose a good place for a nocturnal animal to live.

Which of the following is the best choice?

• An area with low light year-round

• An area with bright light year-round

• An area where the light changes throughout the year

• None of the above; light will not affect how well the animal will sense its surroundings
