1

the organism had three toes

the organism could fly

the organism was a dinosaur

the organism was a bird

Based on these footprints, you decide that the organism started to run. Your idea is known as:

data

an inference

an experiment

an observation

1

What kind of information can you collect from these footprints?

A population of birds eats the green moths that live in a pine forest. Every so often, the green moths have a brown offspring. The brown moths are usually seen more quickly by the birds and eaten sooner. The fact that the brown moths are easier to see and are less likely to survive as a result is known as:

evidence

mutation

variation

natural selection

1

A population of birds eats the green moths that live in a pine forest. Every so often, the green moths have a brown offspring. The brown moths are usually seen more quickly by the birds and eaten sooner. Which of the following statements is TRUE?

the brown moths are possibly a result of a mutation

the brown moths increase the variation within the moth population

both a and b

none of the above

1

A population of birds eats the green moths that live in a pine forest. Every so often, the green moths have a brown offspring. The brown moths are usually seen more quickly by the birds and eaten sooner. The green moths survive in the forest because:

their coloring makes them better adapted to their environment than the brown moths

they fly faster than the brown moths

both a and b

none of the above

1

A population of birds eats the green moths that live in a pine forest. Every so often, the green moths have a brown offspring. The brown moths are usually seen more quickly by the birds and eaten sooner. Imagine that increased pollution caused the pine trees in the forest to be heavily covered with brown particles. What is most likely to happen?

The green moths would survive, but would become covered in brown particles

The green moths would decide to have more brown offspring in order to survive

The green moths would be less likely to be eaten by the birds. Over time, the moth population would still have more green moths.

The brown moths would be less likely to be eaten by the birds. Over time, the moth population would have more brown moths.

Mutations are:

always helpful

always harmful

sometimes helpful, sometimes harmful, sometimes neither

always deadly

A man lifts weights and exercises until he is very muscular. He works out with the hope that his children will also be very strong. A problem with this idea is that:

characteristics that are acquired during one’s lifetime cannot be passed on to offspring

not all offspring want these new characteristics

these characteristics may make the offspring less likely to survive

offspring are born weak

1

A man lifts weights and exercises until he is very muscular. He works out with the hope that his children will also be very strong. To insure that his children are strong, which of the following should the man do?

have children with a woman who also works out

have children with a woman who is stronger than him

help his children exercise to build muscle

have his children look at his muscles

1

Which of the following could describe a mutation in the population?

long-beaked birds have long-beaked offspring

striped cats have striped offspring

beige worms have beige offspring

hornless cows have horned offspring

A female giraffe with a short neck is having a difficult time reaching the leaves in the taller trees. According to the theory of natural selection, which of the following is possible?

The giraffe stretches to reach the taller trees and her neck grows longer. Her offspring all have longer necks.

The giraffe decides that she should have offspring with longer necks. For a mate, she looks for a male giraffe with a long neck.

The giraffe survives on leaves from shorter trees. Her offspring with longer necks are more likely to survive.

The giraffe survives on leaves from shorter trees. Her offspring all have longer necks.

A scientist goes to an undisturbed field and begins digging. She finds a leg bone of Dinosaur A about 12 feet below the surface. She keeps digging and then finds a jaw bone of Dinosaur B about 27 feet below the surface. Based on this information, which is the MOST likely:

dinosaur A lived before dinosaur B

dinosaur B lived before dinosaur A

both dinosaurs are from the same time period

no conclusion can be made

For many generations, a fish population had a lot of color variation. About half of the fish population was white and the other half gray. A species of large fish that eats the smaller fish enters the area. This large fish can see white fish easier than gray fish. What is likely to happen to the color of the fish population? Explain.
