A knife is sharp and has a blade similar to a sharks' tooth. The shark is a carnivore, which means it eats meat, so its teeth are adapted to help them catch and eat their prey. Humans have sharp teeth but need some help cutting up our food. Knives serve the same function as sharks' teeth.

Plants use their roots to absorb water from the ground to help them survive. Humans also need water to survive and a way we mimic (or copy) the way a plant solves this problem is by using a straw. We use a straw to drink water to help us live.

Humans can copy water lilies and use a raft to float on the surface of the water. The leaves of a water lily float on the surface of the water with their flat bottoms so they can absorb sunlight. We can also float on top of the water but we do not have leaves like plants do.

Plants have external structures used for survival. Roots are used to absorb water, the stem keeps a plant upright, leaves are used to absorb sunlight and carbon dioxide to make food, and the flowers are used for pollination.

Animal offspring are similar to their parents because they have many of the same or similar features. They may have the same coloring, eye colors, patterns, but just be a smaller version. They inherit their traits and appearance from their parents, so there is some resemblance.

One human problem that can be solved by mimicking (copying) plants is how we protect our heads on a bicycle. The shells of nuts like the acorn are hard and protect what is inside. Helmets are made to be hard and shaped like our heads to protect us if we fall.

Humans often mimic plants to solve problems in their everyday life. Livestock such as goats or pigs are prey animals and can be eaten if not protected. The thorns on a rose bush will poke or cut something trying to eat it or climb up it. Barbed wire fences will cut or stick something that tries to climb in or out of the pasture.

To mimic someone or something means to copy or act the same as. Little brothers and sisters like to mimic or copy older siblings to annoy them! Humans also mimic plants and animals to solve problems.

This is a true statement. Humans look at how plants use their external parts to survive and copy those features to help us in our own lives.

Plants are useful to humans because they are able to mimic or copy their structures for survival. We can copy their thorns or the way they float and use that information to make ways for us to do the same things.

The roots of a plant keep it stable and in place. Humans have mimicked or copied this survival strategy and used it to keep our houses in place and stable. Without strong roots or a strong foundation the plant or home would fall over.

There are many parts of a plant that humans use to solve their own problems and make new items. Rafts, helmets, fencing, and more are all modeled after plant parts.

Offspring is the young of a plant or animal. In the example, the mother eagle is taking care of her babies until they leave the nest. Plants and animals reproduce and their babies are called offspring.

The dog and kitten are two different species, so there is no way that the dog is the kitten's mother! They look nothing alike and are not the same animal, so that is a big clue! Animal parents and their offspring have to be the same species and will have some things in common.

The main difference between the two elephants is their size. The adult and baby both have similar coloring, ear shape, trunks, and builds. The mother elephant is much larger than its offspring.

The mother tiger and her offspring are similar in their coloring, pattern, features, and builds. They are different because of their size. The adult tiger is much larger than the baby tiger.

The cat that is most likely his mother is very similar to him. Animal offspring are similar to their parents and will have features that are alike. There will be some differences

Animal parents and their offspring do not look exactly the same. Baby animals inherit traits from both parents and are not the same size as adult animals.

Humans are mimicking animals' ears and eyes to help us keep our own houses safe. Many animals have excellent hearing and vision, and this keeps them safe from predators, especially at night. Humans cannot see in the dark, so motion detectors and lights help us to see cameras record what happens so we can watch it. The alarm system acts like eyes and ears to keep us safe.
