Example Questions

Example Question #1 : Describe How Animals Receive Information

Animals have different sense receptors that are specialized for particular kinds of information.

Possible Answers:

False

True

Correct answer:

True

Explanation:

This is a true statement. Animals have specific receptors that do a specialized job. Animals use their five sense just like humans to take in information that later is processed. They may have different levels of abilities with the senses (exceptional eyesight, night vision, echolocation, etc.), but they all use them to receive information.

Example Question #2 : Describe How Animals Receive Information

Mr. Murphey's class went outside and lined up shoulder to shoulder. Mr. Murphy stood at the end of the line, and he read a sentence aloud from a book. The students complained they couldn't hear if they were not right next to him. He told them to act like a white-tailed deer and cup their hands behind their ears to amplify the sound. They moved their cupped hands towards Mr. Murphy, and when he read the sentence, most students could hear him. He kept walking backward away from the line and repeated the sentence until he was about 200 feet away, and no one could listen to him. When they returned to class, Mr. Murphy asked the class a question.

What was the adaptation that deer have to help them hear soft sounds in the forest?

Deer, Doe, Nature, Wildlife, Fawn

Possible Answers:

Cupped hands

Sound muting ears

Sound collecting ears

Sound muffling ears

Correct answer:

Sound collecting ears

Explanation:

This classroom investigation is a great hands-on way for students to see how animals receive information. Deer are prey animals and are always on the look-out for predators. Their massive sound collecting ears are perfect for amplifying or increasing the volume of soft noises in the woods. A predator will try to ambush or sneak up on a deer, so they walk very slowly and carefully. The deer can hear even the slightest crackling of leaves or sticks, and this advantage may very well be what keeps them alive.

Example Question #3 : Describe How Animals Receive Information

Predators and prey are built differently and receive information in unique ways. A predator has eyes on the front of its head; you can mimic this by holding your hands in a binocular fashion and putting them up to your eyes. A prey animal has eyes on the side of its head. You can mimic this by making the binocular shapes with your hands and crossing your arms (your left hand will be over your right eye and your right hand over your left eye). You will notice that the predator has forward-facing vision but limited peripheral vision, and it is the opposite of the prey animal.

Why would these animals need to receive information differently?

Possible Answers:

Predators need to see directly in front of them for hunting, while prey animals need to see all around them for threats.

Prey animals need to see directly in front of them for hunting, while predators need to see all around them for threats.

They do not need to see differently.

Predators need to see around them for hunting, while prey animals need to see in front of them for threats.

Correct answer:

Predators need to see directly in front of them for hunting, while prey animals need to see all around them for threats.

Explanation:

Prey animals spend their whole lives trying to avoid being eaten by a predator. Predators exert immense amounts of energy to hunt prey animals and get a meal. Their vision is ideally suited for their specific lifestyles and tasks. A full, board field of view will help a prey animal like a gazelle see all around it while it grazes. A cheetah has zeroed in on the gazelle with its forward-facing binocular like vision. Each animal has eyes to receive information for their need and adaptations.

Example Question #1 : Describe How Animals Receive Information

Mice, cats, dogs, and other mammals have a unique feature to help them receive information. They have __________ on their faces that sense vibrations to help them stay safe or find prey.

House Mouse, Mouse, Long Tailed Mouse

Possible Answers:

eyebrows

eyes

cheeks

whiskers

Correct answer:

whiskers

Explanation:

Whiskers are a unique feature that mammals have to detect vibrations in the ground and air. Animals such as mice will stop and sniff the air for scents but also sense any movement from a possible predator through their whiskers. Animals will also use their whiskers to feel the air current, and when there is limited light, they will use the whiskers to judge the size of an opening or hole to determine if they can fit. Their whiskers are continually picking up information for their brain to process.

Example Question #1 : Describe How Animals Receive Information

Sugar gliders are nocturnal animals that live in the jungle. At night they must not only find fruit to eat but also avoid predators. They have incredibly large eyes. These eyes are an adaptation for animals that are active at night. Pupils in the eye will dilate and contract to allow more or less light depending on the situation.

Why do the sugar gliders need such large eyes?

Australian Wildlife, Sugar Glider

Possible Answers:

They need large eyes to receive more light in the daylight.

They need large eyes to receive less light in the darkness.

They need large eyes to receive less light in the daylight.

They need large eyes to receive more light in the darkness.

Correct answer:

They need large eyes to receive more light in the darkness.

Explanation:

Nighttime in the jungle can be a scary place because it is incredibly dark. The thick canopy blocks out light from stars, the Moon, and nearby cities. As sugar gliders travel through the trees to find food, they need to see where the branches are for their next landing and if there is a predator approaching. Their large eyes are adapted to receive information from their surroundings. Their pupils will dilate, making their eyes look almost entirely black to allow more light into the eye. This adaptation helps the sugar glider find food and be on the look-out for predators.

Example Question #1 : Describe How Animals Receive Information

True or false: The way an organism gathers information depends on the organism and its individual body structures.

Possible Answers:

False

True

Correct answer:

True

Explanation:

Many animals, like humans, have sense organs that gather information from the environment through seeing, hearing, feeling, smelling, and tasting. Some animals have sensory receptors or other mechanisms that allow them to sense such things as light, temperature, moisture, and movement. Because animals live in different environments from one another and have multiple different types of prey/predators, they must gather information in different ways, which best benefits their species.

Example Question #2 : Describe How Animals Receive Information

True or false: Animals’ use of their senses is not critical to their survival.

Possible Answers:

True

False

Correct answer:

False

Explanation:

Explanation: Most animals rely heavily on their senses to help them survive. The senses are how the majority of animals receive information about their surroundings. Their senses assist with hunting, reproducing, migration, and several other essential aspects of animal life. Without the senses, many animals could quickly find themselves struggling to survive.

Example Question #2 : Describe How Animals Receive Information

Coyotes are a species which has excellent vision and a strong sense of smell. To hunt more effectively, they form packs and use these features to locate and attack their prey. They can run up to 40 miles per hour and communicate with one another using a set of howls. These howls might warn of danger or can tell other coyotes their exact location. Coyotes are considered to be destructive but extremely smart animals.

Which of the following sets of features BEST describes how coyotes receive information?

Possible Answers:

Smell and speech

Echolocation and vision

Vision and speech

Smell and vision

Correct answer:

Smell and vision

Explanation:

The passage explains how coyotes use their senses of smell and sight to hunt their prey. Without these features, coyotes would not be considered formidable predators; however, with these senses combined with their pack mentality, they are. They rely heavily on these senses to receive information that helps them survive.

 

Example Question #6 : Describe How Animals Receive Information

Which of the following is NOT an example of a feature an animal may use to receive information about its surroundings?

Possible Answers:

Stomach

Sight

Ears

Whiskers

Correct answer:

Stomach

Explanation:

Animals have many different features that they use to receive information about their surroundings. For example, a cat can use its whiskers to determine whether its body would fit through a tight space. Moths use their sense of hearing to avoid being hunted by bats. Birds of prey have long-distance sight to be able to spot prey from far away.

Example Question #3 : Describe How Animals Receive Information

Jellyfish are unique animals in the sense that they don’t have bones, a brain, or a heart. What they do have rudimentary sensory nerves at the base of their tentacles, which allow them to see light, detect smells, and orient themselves. They do not intentionally sting people to attack because their nervous systems are extremely simple. Instead, the sting is intended to be both a defense mechanism against any creatures it may come into contact with, and also a way to capture potential prey.

Which of the following features does a jellyfish use to receive its information?

Possible Answers:

Brain

Tentacles

Bones

Heart

Correct answer:

Tentacles

Explanation:

The passage describes how jellyfish are unique because they don’t have many of the features that most animals do have. However, they have tentacles that serve multiple purposes. They contain sensory nerves that allow jellyfish to see light, smell, and determine if an object is potential prey.
