What do all animals need? (Must name at least two.)
Nearly all animals need water, oxygen, food, and shelter.
100
What is the purpose of the pupa?
A pupa develops into a butterfly.
100
Give two examples of adaptations and tell how they help the animal survive.
Examples: webbed feet for swimming, teeth fit for eating meat, and short, strong bills for breaking open seeds.
100
What are some ways that fossils form? (Name at least two.)
1. Animal parts are covered with material, which hardens around it. When the parts wear away, a mold is formed. 2. Rock matter can fill the space left behind by the body part, forming a cast. 3. Tree sap covers an insect and hardens.
100
What is a trait?
A body feature passed on to an animal from its parents.
200
Should reptiles and amphibians be grouped together? Explain.
Amphibians and reptiles can be grouped together in a general way because they both have backbones. But they should be in separate groups because amphibians can breathe with gills or through their skin and reptiles cannot.
200
List the sequence of steps in a butterfly's life cycle.
1. Egg 2. Larva 3. Pupa 4. Butterfly
200
What are some ways that animals protect themselves from their enemies?
Camouflage, armor, mimicry, and poison.
200
Describe four kinds of fossils.
Mold - impression formed in rock Cast - filled in mold Animal trapped in amber Animal trapped in tar pit
200
What is a vertebrate?
An animal with a backbone.
300
Name the five groups of vertebrates.
Fish, amphibians, reptiles, birds, mammals
300
Before a frog can live on land, how must its body change?
A frog must grow lungs so that it can breathe air and powerful legs to propel its self forward.
300
Name two types of adaptations having to do with an animal's actions.
Examples: opening a mouth for food, migrating, hibernating, escaping, and hiding from enemies.
300
What can fossils tell us about extinct animals?
Fossils can tell us how extinct animals looked and the kind of environment extinct animals lived in.
300
What is a larva?
Another name for the stage of a butterfly when it hatches into a caterpillar.
400
If a rattlesnake and a black widow spider both make poison, why are they put in different groups?
A rattlesnake has a backbone, but a spider does not.
400
How is a mammal's life cycle different from a frog's or a butterfly's life cycle?
A mammal's egg develops inside its mother, is born looking like its parents, and does not change a lot in its life cycle. A frog or butterfly egg develops and hatches outside the mother and changes a lot in its life cycle.
400
Why do some animals migrate or hibernate?
Animals migrate or hibernate when the seasons change in order to survive.
400
What modern day animal looks like dinosaurs long ago?
A lizard
400
What is an adaptation?
A trait that helps an animal meet its needs in the place it lives.
500
Explain why most invertebrates are small in size compared to most vertebrates.
The invertebrates' structures give less support than bones. A large body needs support; otherwise, it would collapse.
500
Describe what kind of care might be helpful for most mammals.
Examples: Young mammals are fed and protected until they learn how to live on their own and grow large enough to protect themselves.
500
How are chimpanzees and humans alike in the ways that they learn?
Humans and chimpanzees are alike because both live in groups and learn from others in their group, usually from the adults.
500
Fossils tell us about what plants and animals lived long ago. What do fossils tell us about the Earth?
Fossils tell us how Earth has changed over time.
500
Define inherited.
Adaptations passed on from parents to their young.
