A scientist discovers a fossil of an animal and places it in the fossil record. The organism’s bones are similar to the bones of animal T, which appears earlier in the fossil record. Which conclusion is most reasonable?(1 point)

The fossils came from the same organism.

The fossils are from an ancestor of animal T.

The fossils are from animals that lived at the same time.

The fossils are from a descendant of animal T.
2. Why do organisms evolve?(1 point)

Organisms naturally select traits that help them survive and reproduce.

Organisms with traits that help them survive and reproduce in their environment pass on those traits.

Changes in the environment cause organisms to change.

Organisms make changes to help them survive and reproduce in their environment.
3. Scientists examine fossils from three different animals. They determine that all three animals share similar structures and record their observations as follows:

Animal A and animal B have somewhat similar structures.
Animal A and animal C have very similar structures.
Animal B and animal C have very similar structures.
The scientists use the similarities to determine the order in which the fossils should appear in the fossil record. Based on the scientists’ observations, which order is the most reasonable?

(1 point)

B, A, C

A, C, B

A, B, C

C, B, A
4. Scientists discover fossilized bones from two different animals. The scientists consult the fossil record to learn more about the fossils. Which question will the fossil record best answer?(1 point)

Why do you, as a living organism, need to continually consume food?

Choose 1

answer:

(Choice A) A Food is broken down by catabolic pathways and converted to ATP, which is then used to fuel anabolic pathways.

(Choice B) B Food is broken down by anabolic pathways and converted to ATP, which is then used to fuel catabolic pathways.


(Choice C) C Food is broken down by endergonic reactions and converted to ATP, which is then used to drive exergonic reactions.
