Yellowjackets use their senses to find food, like rotting fruit. When looking for food, the yellow jacket flies around and uses its eyes to see how far away objects are. It flies close to an object and uses the antennae on its head to smell the object. If the object is a fruit, then it uses its legs to land and hold on to it. The yellowjacket uses its mouth to eat the fruit, then flies away.


How does a yellow jacket use its senses to determine if an object is food? 

A. It uses its mouth to taste the object to determine if its a fruit

B. It uses its eyes to see how far away it is from the fruit

C. It uses its antennae to sniff an object to determine if its a fruit

D. All of the above 

D. All of the above

Which statement best describes how a rabbit processes information that is taken in by the rabbit’s eyes?

A. A rabbit’s eyes send images to its brain so that the rabbit can see a place to hide.


B. A rabbit’s eyes send signals to its muscles so that the rabbit can run from danger.


C. A rabbit’s eyes send signals to its brain so that the rabbit can decide how to respond.


D. A rabbit’s eyes send images to its ears and nose so that the rabbit can take in more information.



C. A rabbit’s eyes send signals to its brain so that the rabbit can decide how to respond.

How is an innate behavior different than a learned behavior?

An innate behavior is a behavior that you do not have to learn how to do. You are born knowing how to do it.

Many rabbits, like the one below, have very long ears, eyes on both sides of the their head, and very strong back legs.

Which of the following best explains why rabbits have long ears?

A to help them find plants to eat

B to protect them from snow

C to look for a good habitat

D to notice predator sounds



D to notice predator sounds

This diagram shows the process the body uses to respond to information received through the senses. 


Which of the following best describes the missing step 2?

A. Information stored for later use

B. Information sent to the brain

C. Body systems respond to information

D. Receptors respond to the information




b. Information sent to the brain

What is “information”?

Details about the environment that an animal can sense

How is a sensory structure different from other structures?

A structure is ANY part of an animal’s body that has a specific purpose.

A sensory structure is a part of animals body that allows it to get information from its environment using one of its senses.

An animal must avoid eating the poisonous berries in its environment. The poisonous berries look, feel, and taste the same as the berries that are not poisonous. Choose a sense that could help the animal detect which berries it should not eat. 

  1. With taste buds, the animal could eat the berries and taste which ones are poisonous.

  2. With specialized eyes, the animal can see which berries are poisonous and which are not.

  3. With a strong sense of smell, the animal can smell the berries to determine which are poisonous.

  4. With sense receptors on the fingers, the animal could feel the berries before eating them to determine if they are poisonous or not.



C. With a strong sense of smell, the animal can smell the berries to determine which are poisonous.

Gazelles with short legs are caught and eaten by predators more often than gazelles with longer legs. This observation would best support which of the following ideas?

A Longer legs help gazelles escape predators.

B There are no gazelles with very long legs.

C All types of predators run faster than all gazelles.

D Gazelles with short legs live longer than others.





A Longer legs help gazelles escape predators.

Cuttlefish have several structures on the outside of their bodies that help them survive.

  • Eyes that change shape to allow the cuttlefish to see better in the dark.

  • Special skin that helps the cuttlefish change color, pattern or shape.

  • The cuttlefish also has a special “W” shape to the center of its eye called a pupil. Although it is colorblind, the cuttlefish uses this special part of its eye to sense changes in its environment. When there is less light, the cuttlefish changes its entire eye shape to let more light in.


In which ways do two body structures of the cuttlefish work together to help the cuttlefish survive? Select the two correct answers.

A. The skin changes colors while the “W” pupil helps the cuttlefish notice changes in light.

B. The inside shell helps grab predators while the skin changes shape for protection.

C. The skin helps the cuttlefish change patterns while the tentacles distract predators.

D. The fins are used for sensing colors while the cuttlebone moves the cuttlefish forward.


A. The skin changes colors while the “W” pupil helps the cuttlefish notice changes in light.

C. The skin helps the cuttlefish change patterns while the tentacles distract predators.

Cuttlefish have many sight receptors and even have them in their skin. This allows cuttlefish to notice and identify predators from far away. They also send information to the brain. The cuttlefish’s brain decides how it should respond.

Which statement best explains why a cuttlefish could notice a predator swimming overhead faster than a deep sea fish? 

A. The cuttlefish has sight receptors all over its body but has less sight receptors than a deep sea fish.

B. The cuttlefish can get more information from its eye and skin receptors to learn about their environment.

C. The cuttlefish has a smaller set of sight receptors than deep sea fish and only has them on the end of its tentacles.

D. The cuttlefish only has sight receptors in its eyes but has many more sight receptors than a deep sea fish.







D. The cuttlefish only has sight receptors in its eyes but has many more sight receptors than a deep sea fish.
