Question 20

A scientist compares DNA taken from four different living species. Which of the following statements is true?

Accepted Answer

Species A and Z share a recent common ancestor.

Answer

Species X evolved from Species Y.

Answer

Species A and Species Y are the same.

Answer

Species Y and Species Z can interbreed.

Question 21

The diagram illustrates an embryonic stage of two organisms. Which of the following can be determined by observing the embryos shown in the diagram?

Accepted Answer

The organisms share a common ancestry.

Answer

The organisms belong to the same genus.

Answer

The organisms are native to the same geographic areas.

Answer

The organisms will grow into anatomically similar adults.

Question 22

How can the pattern of change in the fossil record best be explained?

Accepted Answer

The mollusks were well adapted to their stable environment. A large, sudden change occurred in their environment. After the change the mollusks with the bigger shells were better adapted for the new environment.

Answer

The mollusks were well adapted to their stable environment. The mollusks hybridized with a smaller species of mollusk. A new species of mollusk with a bigger shell resulted.

Answer

The mollusks were not well adapted to their environment. The length of the mollusks' shells changed gradually over time. The mollusks in the original population that had small shells died over a period of many years.
