Which characteristic best distinguishes these cells as either prokaryotic or eukaryotic?

• The function of the flagella

• The location of the cytoplasm

• The role of the cell membrane

• The organization of of the genetic material

When a stem cell divides, it produces two daughter cells. One daughter cell will remain a stem cell, while the other daughter cell will differentiate into a specialized cell.

Which factor will most directly determine what type of specialized cell will be produced?

• The size of the cell

• The length of the cell cycle

• The number of chromosomes that are replicated

• The genes that are expressed

Certain species of the coral-like sea organisms called bryozoans first appeared about 140 million years ago. They remained unchanged for the first 40 million years and then suddenly experienced rapid genetic change.

Which process would BEST account for the pattern of evolution in bryozoans?

• Convergent evolution

• Differentiation

• Punctuated equilibrium

• Gradualism

Two scientists studied patterns of evolution in the fossil record. Many species they analyzed showed periods of slow changes interrupted by a period of rapid change.

This pattern of periods of slow change interrupted by periods of rapid change with few, if any transitional fossils, best describe the theory of-

• Natural selection

• Genetic drift

• Punctuated equilibrium

• Gene flow
