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?

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

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

Animals are not able to use their perceptions and memories to respond to situations.
Animals are not able to use their perceptions and memories to respond to situations.
This statement is false. Animals do use their memories and perceptions to help them respond to situations. If an animal has been bitten or injured, it will remember that encounter and avoid that same dangerous place or animals. Older chimpanzees will teach the young monkeys about snakes and how dangerous they are. They will show them how to holler and hit them with sticks to scare them off. The babies remember this and not only apply it to their own life, but they teach it to their offspring too.

Platypus have a "sixth-sense" that allows them to hunt underwater: electroreception. To find meals in the mud, it uses its bill to detect movements and subtle electric fields produced by its prey. Receptors on the bill detect changes in pressure and motion. Two types of receptors track the electrical signals produced by small prey when they contract their muscles. The platypus moves its head side-to-side to determine the direction and distance of its next meal by collecting and processing this sensory information. The platypus has about 40,000 of these special receptors.

Electroreception is an internal structure. Internal structures are the inner pieces and parts which keep animals alive. A platypus cannot survive without electroreception, or, the ability to perceive electrical stimuli.

Which structure on a plant aids in survival by absorbing water?
Which structure on a plant aids in survival by absorbing water?
The plant has internal and external structures that aid in survival. The roots absorb water from the soil and keep the plant steady and stable, so it doesn't fall over. Without the roots, the plant would topple over and be dehydrated because of a lack of water.

How do the leaves on a plant assist in its survival?
How do the leaves on a plant assist in its survival?
The leaves on a plant are an external structure that assists in its survival. Without leaves, plants would not be able to make their food through the process of photosynthesis. The leaves absorb carbon dioxide and sunlight to turn into food for the plant. This structure is vital to a plant living and growing.

How do flowers aid in a plant's survival?
How do flowers aid in a plant's survival?
Flowers don't seem vital to a plant's survival, but they are an essential part of the process. They are the main structure for reproduction, so they aid in pollination to continue the development of new plants. Flower petals attract pollinators who then fertilize the plants, seeds are developed, and some plants produce fruits and vegetables, and pollinators are required for this process. Without the flower, all of these things would be impossible.

Darrell says that elephants’ size is the only thing that helps them survive in their habitats. Why is Darrell’s argument wrong?
Darrell says that elephants’ size is the only thing that helps them survive in their habitats. Why is Darrell’s argument wrong?
While animals’ size can undoubtedly assist them in their efforts to survive, elephants have several other structures that they rely on for survival, including their ears and skin, which keep them cool, their trunks which they use to eat and drink, and their tusks that they use for protection.

Animals rely solely on external structures to help them survive.
Animals rely solely on external structures to help them survive.
Animals have many internal structures which they rely on for survival. For example, the lungs, brain, and heart are all internal structures necessary for survival. Some animals have less common internal structures, too, like antifreeze proteins in the blood of Antarctic fish.

True or false: Animals are similar to humans because they both use sense organs to gather information from the environment.
True or false: Animals are similar to humans because they both use sense organs to gather information from the environment.
The way in which an organism gathers information will depend on the organism and the body structures that pick up signals from the environment. 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.

Why is it important that the animals’ brains process and store information?
Why is it important that the animals’ brains process and store information?
Animals rely on their abilities to use sensory programs to stay alive. Their brains process information quickly to help them hunt, stay alive, and reproduce. Animals’ brains, like humans’, store information so they can also reference learned behaviors when similar scenarios arise and make decisions quickly.
