Question 2

Question

A) Why do organisms evolve? (1 point)
Organisms with traits that help them survive and reproduce in their environment pass on those traits.
Organisms naturally select traits that help them survive and reproduce.
Organisms make changes to help them survive and reproduce in their environment.
Changes in the environment cause organisms to change.
Question 3
A)
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)
A, B, C
C, B, A
B, A, C
A, C, B
Question 4
A) 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)
What killed the animals?
Which animal was better equipped to survive?
How are the animals related to modern animals?
Which animal is older?
Question 5
A) How do fossils of the animal Archaeopteryx provide evidence that birds evolved from one
group of dinosaurs? (1 point)
Fossils of Archaeopteryx are older than fossils of birds but younger than fossils of dinosaurs.
Fossils of Archeopteryx have traits that show they were better able to survive than dinosaurs but
less able to survive than birds.
Fossils of Archaeopteryx have traits of both dinosaurs and birds.
Fossils of Archeopteryx were discovered near fossils of both dinosaurs and birds

Question 2
A) Why do organisms evolve? (1 point)
Answer: Organsims with traits that help them survive and reproduce in their environment pass on those traits.

Question 3
A) Based on the scientists’ observations, which order is the most reasonable? (1 point)
Answer: A, C, B
(Evidence suggests that Animal A and C are very similar, making them closely related, followed by Animal B which is less similar.)

Question 4
A) Which question will the fossil record best answer? (1 point)
Answer: Which animal is older?
(The fossil record is primarily used to determine the age of different species and their evolutionary history.)

Question 5
A) How do fossils of the animal Archaeopteryx provide evidence that birds evolved from one group of dinosaurs? (1 point)
Answer: Fossils of Archaeopteryx have traits of both dinosaurs and birds.
(This indicates a transitional form, showcasing characteristics of both groups and supporting evolutionary lineage.)
