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.

The brain is where all information received from the senses is processed.
Animals take in information through their five senses, just like humans. Once the information is received, it is processed for understanding and reaction. The brain is the hub for all processing. The mind will send out messages to the rest of the body with instructions on how to react or behave with the information the five senses collected.

Vipers, pythons, and boas have a special adaptation that allows them to process information uniquely. These snakes can detect infrared radiation from warm bodies up to a meter away. The snakes then build an image of what is emitting this heat to help the snake decide if it should attack or flee. Snakes have poor eyesight, so these pits are vital.
Which sentence demonstrates how the snakes process the information they receive?

Which sentence demonstrates how the snakes process the information they receive?
All of the sentences provide essential information about vipers, pythons, and boas using pits in their heads as infrared radiation sensors. Still, only one demonstrates how the snakes process the information they receive. The holes collect the data, but the snakes' brain processes that data into something usable. "The snakes then build an image of what is emitting this heat to help the snake decide if it should attack or flee." is the sentence that explains how the data is used. An image is built from the information that allows the snake to "see" the figure and decide how to respond.

Echolocation is a behavior in which animals emit calls and then listen to the echoes that bounce back off of stable things in the environment. This behavior can be used to navigate and to find food or mates. Orcas, dolphins, sperm whales, and pilot whales are all creatures that use this function to gather information. They release small bursts of air from air sacs in their heads and then through their mouths. This burst of air will make a click or ringing sound. The sound will bounce off an object and return to the whale or dolphin. That information is then transferred to a centralized place (the brain) where it is processed, and the organism responds in ways that will help it survive and reproduce.

Where is the information processed that whales or dolphins receive?
Whales and dolphins are such unique animals with this extraordinary characteristic. Echolocation is beneficial to these animals because of the depths at which some of them live. It is dark and hard to see to locate prey, so this adaptation assists them with the task. The information that is collected when the sound returns are processed in the brain. The sounds are made from stored air in the sacs and released through the mouth, but this is for sending out chirps. These animals are mammals and do not have gills. The returning information is processed through the brain.

When animals process information they have received, they often store it for use later as memories. These memories help to influence their future actions.
When animals process information they have received, they often store it for use later as memories. These memories help to influence their future actions.
This is a true statement. When animals receive information, it is processed through the brain. Many times the brain will store this information as a memory to help with similar situations in the future. An example we may all experience is touching something hot. If I touch a hot stove and burn my hand, I will remember in the future not to touch the hot stove again. This is a way to help ensure survival and the furthering of a species or family group.

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.
Based on the passage, which of the following sentences best describes how the platypus processes an electrical signal?

True or false: A chameleon changing colors is an example of an animal processing information.
True or false: A chameleon changing colors is an example of an animal processing information.
A chameleon changing colors is a perfect example of the nervous system (brain) at work. When the chameleon’s skin experiences a change in temperature or mood, its brain processes the shift and reacts appropriately by expanding and contracting cells that contain pigment sacs. Just like any other animal, the chameleon is reliant on its mind to process external stimuli.

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.

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?

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.

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?

Why would these animals need to receive information differently?
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.

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.
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.
