Argue that animals have structures for survival - 4th Grade Science

Owls are excellent hunters and have unique structures that allow them to excel. They have keen eyesight, a sharp beak, and sharp talons on their toes. They hunt at dusk and night when there is low light, and their eyes are suited to see well in the setting. Owls will swoop down on small mammals in the grass and grab them with their sharp talons. Their beaks are sharp and pointed to eat meat. They are built to hunt and are a top predator in their environments.

All of the answer choices are arguments for giraffes being survivors in their habitats, but only one correctly explains why internal or external structures assist them. "Giraffes have features like spots and long necks. The dark spots on a giraffe's body hide an intricate network of blood vessels and glands. These dark patches allow blood to flow through them, releasing heat and cooling the body. A giraffe's long neck helps them reach leaves far up in the treetops where other animals cannot reach. The tallest trees usually have the deepest roots and can reach water in the soil that other trees cannot, so the long neck allows giraffes to reach food sources that last through extended droughts." The structures highlighted in this answer choice are spots and long necks, which are both external features. The choice explains why the spots and long necks are an advantage for the giraffe. This argument includes the necessary information, is accurate, and focuses on the animal structures.

Animals have internal and external structures that help them to survive. Their coats are an example of these types of structures. The fur of an animal can help it hide if it has camouflaging characteristics (tigers), it can look like a warning to predators (skunks), or be thick for warmth and protecting organs from bites (bears). They may have a pretty appearance, but it is not the primary function of the fur.

The rattlesnake pictured has all three of the structures listed for survival and more! Snakes use their tongues as a way to "taste" or "touch" the air to receive sensory information; they have colored scales that can act as a warning to other predators or even as camouflage in their habitat. Rattlesnakes are unique in that they have a rattle on the ends of their chair that they can shake and vibrate as a warning to predators to stay away. These structures help snakes to survive in challenging places.

Andy is arguing that skin cannot help an animal survive, but he can be proven wrong. Many mammals, such as armadillos, hedgehogs, and porcupines, have protective skin features, such as quills and bony plates. These features of skin not only protect the animals from predators but also harsh habitats.

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 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.

Antlers are an example of an external structure that animals may use for protection or fighting. Fur patterns can help animals camouflage themselves as protection. Lungs help an animal breathe in its environment.

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.

Animal structures, both internal and external, are essential features to keep animals alive. Jacob is correct in this argument. Animals have both types of structures to help them survive. Animals like the elephant have trunks that they use as a tool to grab food or spray water and internally they lungs, hearts, and other organs that keep them alive. Without both sets of structures, animals would not be able to live.
