Question 1

Which of the following best describes the difference between quantitative and qualitative data in a biological study?

Accepted Answer

Quantitative data is numerical and can be graphed, such as the number of leaves on a plant, while qualitative data is descriptive, such as the color of those leaves.

Question 2

In the scientific process, which of the following is a characteristic of a testable hypothesis?

Accepted Answer

It can be evaluated by collecting and analyzing data from controlled experiments.

Question 3

Which of the following is NOT one of the seven properties of life illustrated in Figure 1.2?

Accepted Answer

Movement

Question 4

A controlled experiment is designed to test the effect of a single variable. In a study testing the effect of fertilizer on plant growth, which factor should be kept constant?

Accepted Answer

Amount of sunlight each plant receives

Question 5

Which of the following best describes the difference between the movement of energy and the movement of chemicals in an ecosystem?

Accepted Answer

Energy flows through the ecosystem and is eventually lost as heat, while chemicals cycle within the ecosystem.

Question 6

Which of the following is a correct definition of a eukaryotic cell?

Accepted Answer

A cell that contains a nucleus and membrane-bound organelles.

Question 7

In the hierarchy of biological organization, which level comes directly below 'Organisms'?

Accepted Answer

Populations

Question 8

Which of the following statements about gene expression is correct?

Accepted Answer

Gene expression is the process by which information from a gene is used to synthesize a functional product, such as a protein.

Question 9

Which of the following is an example of negative feedback in biological systems?

Accepted Answer

Insulin lowers blood glucose levels when they rise above normal.

Question 10

Which two domains are prokaryotic, and which is eukaryotic?

Accepted Answer

Bacteria and Archaea are prokaryotic; Eukarya is eukaryotic.

Question 11

Darwin proposed natural selection as the mechanism of evolution. Which of the following best summarizes this process?

Accepted Answer

Individuals with traits better suited to the environment are more likely to survive and reproduce, passing those traits to offspring.

Question 12

Which of the following is a property of life that is illustrated by a plant growing toward sunlight?

Accepted Answer

Response to the environment

Question 13

Which of the following best describes a scientific theory?

Accepted Answer

A scientific theory is a well-substantiated explanation that incorporates facts, laws, inferences, and tested hypotheses.

Question 14

Which of the following is an example of a hypothesis that is NOT testable?

Accepted Answer

If unicorns exist, then they can fly.

Question 15

Which of the following best describes the process of gene expression?

Accepted Answer

DNA is transcribed into RNA, which is then translated into protein.

Question 16

Which of the following levels of biological organization includes all living and nonliving components in a particular area?

Accepted Answer

Ecosystem

Question 17

Which of the following is a correct statement about prokaryotic cells?

Accepted Answer

Prokaryotic cells lack a nucleus and membrane-bound organelles.

Question 18

Which of the following is an example of positive feedback in biological systems?

Accepted Answer

Blood clotting accelerates until the wound is sealed.

Question 19

Which of the following best describes the difference between microevolution and macroevolution?

Accepted Answer

Microevolution refers to changes within a species over time, while macroevolution refers to the origin of new species and higher taxonomic groups.
