List some traits that all animals have in common

All animals are organized in their makeup, with cells, molecules, and DNA. All animals develop and grow. All animals reproduce and respond to the environment. No animals can make their own food.

What are some ways that animals can adapt to its environment?

An animal can adapt to its environment by camouflaging or mimicking so that it blends or can hide from predators. Over time, some animals have gotten thicker fur for cold weather or thinner fur for hot weather. The shape of their nose or ears, the number of fingers, the color of fur, or the shape of a bird's beak are some other adaptations.

How are animal behaviors that are inherited different from those that are learned?

Inherited behaviors are reflex and instinct. The animal is born with these behaviors and does not have to be taught them. A reflex behavior can be like a monkey pulling its hand away when it's bitten. An instinct is like a colt being able to walk right after it is born. Learned behaviors are taught by a parent. An example is where an animal learns that an action could lead to good or bad results. A child learns that touching something hot could cause pain.

What are the benefits of crossbreeding? What is an example of a cross breed?

People crossbreed to produce hearty crops or plans and animals with desirable traits. Mules and London plane trees are examples of cross breeds.

Why is diversity important for an animal group to survive?

Diversity is important because if every single animal had the same traits, they may all die out. If they don't have the same traits, then some will survive and keep the population going.

How would you design an experiment to test the reaction of sow bugs to temperature?

First, I would get 3 sow bugs. I would put them in jars with air holes. I would put the first one in the fridge. I would put the second one outside, if it's summer time. I would put the third one in the house. I think the one in the fridge will die and the one outside will live. The one inside will probably die because the air isn't as good inside.

Are bats more closely related to bears or birds? Why?

Bats are more closely related to bears because they are mammals.

You are interested in the inherited and learned behaviors of cats. How might you learn more?

I would look on the internet for more information. The internet has more details than a book does.
