Accepted Answer

Make a prediction based on her hypothesis

Question 4

Which of the following statements about the cell theory is FALSE?

Accepted Answer

Viruses are considered living because they are made of cells.

Question 5

Which level of biological organization is correctly matched with its example?

Accepted Answer

Cellular level – mitochondrion

Question 6

Which of the following best describes the relationship between structure and function in biology?

Accepted Answer

Understanding the structure of a biological molecule can provide insight into its function.

Question 7

Which of the following is an example of evolutionary adaptation?

Accepted Answer

A population of insects developing resistance to a pesticide over several generations.

Question 8

Which domain of life includes organisms that are single-celled and lack a nucleus, but are genetically more similar to eukaryotes than to bacteria?

Accepted Answer

Archaea

Question 9

A researcher is studying the effect of a new drug on bacterial growth. She sets up two groups: one receives the drug, and the other does not. What is the purpose of the group that does not receive the drug?

Accepted Answer

It is the control group, used for comparison.

Question 10

Which of the following best explains why the fossil record is considered evidence for evolution?

Accepted Answer

It reveals transitional forms that link ancient and modern species.

Question 11

Which reasoning method is used when a scientist observes that all swans she has seen are white and concludes that all swans are white?

Inductive reasoning

Question 12

Which of the following is a correct statement about scientific theories?

Accepted Answer

They are well-supported explanations based on extensive evidence.

Question 13

Which of the following best describes natural selection?

Accepted Answer

The process by which individuals with advantageous traits survive and reproduce more successfully.

Question 14

A population of bacteria is exposed to an antibiotic. Over time, most bacteria die, but a few survive and reproduce. What is the most likely explanation for this observation?

Accepted Answer

Some bacteria had a genetic variation that made them resistant to the antibiotic.

Question 15

Which of the following best illustrates the concept of evolutionary conservation?

Accepted Answer

The structure of cilia is similar in both single-celled protists and human respiratory cells.

Question 16

Which of the following is an example of a model in biology?

Question 17

Which of the following best describes the genome of an organism?

Accepted Answer

The complete set of genetic instructions in an organism.

Question 18

Which of the following is an example of a real-world application of systems biology?

Accepted Answer

Studying how the interactions between genes, proteins, and metabolites affect cancer progression.

Question 19

Which of the following best explains why homologous structures are evidence for evolution?

Accepted Answer

They indicate a common ancestry due to similar underlying anatomy.

Question 20

Which of the following is an example of deductive reasoning in biology?

Accepted Answer

All mammals have hair. A whale is a mammal. Therefore, a whale has hair.
