Sensory receptors in the skin have a different structure than sensory receptors in the eye. The most reasonable explanation for the difference in the structure of these receptors is that –

• receptors in the skin are connected to nerve cells, but receptors in the eye are not.

• receptors in the eye respond to a different type of input than receptors in the skin.

• there are many more sensory receptors in the skin than receptors in the eye.

• only the sensory receptors in the eye transmit signals directly to the brain.

Which of the following is the best example of how storing sensory information can benefit an organism?

• Birds that get sick from eating monarch butterflies will avoid eating butterflies with the same coloration.

• When a fire approaches, animals can sense the heat and are able to escape and avoid being harmed.

• Some male moths are able to use chemicals emitted by the female to find them, even from many miles away.

• Many predators have very good hearing that allows them to detect the movement of their prey.

The illustration below shows the structure of the human eye. The sensory receptors on the back of the eye react to light. The pupil is a hole in the iris, a structure in the front of the eye. Movements of the iris can cause the pupil to become larger or smaller. What observation would provide evidence for the claim that, by controlling the size of the pupil, the iris controls the amount of light that reaches the receptors in the eye?

• There are no sensory receptors directly on the pupil at the front of the eye.

• Shining a bright light directly away from the eye causes no change in the pupil.

• Other animals, such as fish and cats, have a pupil with a very different shape.

• The pupil becomes larger in dim light and smaller in bright light.

What is the most precious sense we have?

• Taste

• Sight

• Smell

• Hearing
