Accepted Answer

Cell Theory

Question 4

Louis Pasteur’s experiment disproved the hypothesis of spontaneous generation. What was the key variable that differed between his two treatments?

Accepted Answer

Exposure to preexisting cells

Question 5

Which statement correctly describes the two components of a scientific theory?

Accepted Answer

Question 6

According to the complete cell theory, which of the following statements is true?

Accepted Answer

All cells come from preexisting cells.

Question 7

The theory of evolution by natural selection states that:

Accepted Answer

Species are related by common ancestry and evolve by natural selection.

Question 8

Artificial selection in the cabbage family demonstrates which principle of evolution?

Accepted Answer

Heritable traits can be selected to change population characteristics over time.

Question 9

Which of the following best describes the role of heritable traits in natural selection?

Accepted Answer

Heritable traits lead to increased success in producing offspring, changing population traits over time.

Accepted Answer

He kept all conditions identical except for one variable.

Question 11

Which of the following is a graphical representation of evolutionary relationships among species?

Accepted Answer

A phylogenetic tree

Accepted Answer

Charles Darwin

Question 14

Which process is responsible for the change in characteristics of a wild population over time?

Accepted Answer

Natural selection

Question 15

Which of the following is NOT a key concept that founded biological science?

Accepted Answer

Theory of Relativity

Question 16

If a population of wild plants is exposed to a new environmental pressure, which of the following is most likely to occur over generations?

Accepted Answer

Individuals with heritable traits that confer an advantage will become more common.

Question 17

Which of the following equations best represents the relationship between genotype and phenotype in the context of heritable traits?

Accepted Answer

$$	ext{Phenotype} = 	ext{Genotype} + 	ext{Environment}$$

Question 18

Which of the following best explains why Pasteur’s experiment was considered a controlled experiment?

Accepted Answer

Question, hypothesis, prediction, experiment, analysis

Question 20

Which of the following statements about artificial selection is true?
