Accepted Answer

A hypothesis must be testable and falsifiable.

Question 3

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

Accepted Answer

Extrapolating from the general principle that all cells contain DNA to predict that a newly discovered cell will also contain DNA.

Question 4

Which of the following best illustrates the concept of 'structure and function' in biology?

Accepted Answer

The shape of a bird’s wing enables flight.

Question 5

A scientist wants to test the effect of light on plant growth. She sets up two groups: one exposed to light and one kept in darkness. What is the independent variable in this experiment?

Accepted Answer

The presence or absence of light.

Question 6

Which statement about eukaryotic and prokaryotic cells is correct?

Accepted Answer

Eukaryotic cells contain membrane-enclosed organelles, including a nucleus.

Question 7

Which of the following is a unifying theme in biology?

Accepted Answer

Evolution accounts for the unity and diversity of life.

Question 8

Which process is responsible for the production of proteins that perform many functions in a cell?

Accepted Answer

DNA encodes genetic information that is used to produce proteins.

Question 9

A controlled experiment is designed to test the effect of a single variable. What is the purpose of the control group?

Accepted Answer

To serve as a baseline for comparison with the experimental group.

Question 10

Which of the following best explains why evolution is considered a core theme in biology?

Accepted Answer

It explains both the unity and diversity of life through descent with modification.

Question 11

Which statement about energy flow in ecosystems is correct?

Accepted Answer

Energy flows from the sun to producers and then to other organisms.

Question 12

A scientist observes that a lamp does not work. She hypothesizes that the bulb is burnt out. Which step of the scientific process does this represent?

Accepted Answer

Forming a hypothesis based on an observation.

Question 13

Which of the following is NOT a characteristic of a scientific theory?

Accepted Answer

It is based on a single observation.

Question 14

Which of the following best describes the relationship between science and technology?

Accepted Answer

Question 15

Which of the following is an example of a qualitative observation?

Accepted Answer

Describing the color of a flower.

Question 16

Which statement about the unity and diversity of life is correct?

Accepted Answer

Question 17

Which of the following is a correct description of the dependent variable in an experiment?

Accepted Answer

It is the variable being measured in response to changes in the independent variable.

Question 18

Which of the following is a correct statement about chromosomes?

Accepted Answer

Chromosomes contain a cell’s genetic material in the form of DNA.

Question 19

Which of the following best describes the process of natural selection?

Accepted Answer

It allows organisms with beneficial modifications to survive and produce more offspring.

Question 20

Which equation best represents the transformation of energy in photosynthetic organisms?

Accepted Answer

$$6CO_2 + 6H_2O + light \rightarrow C_6H_{12}O_6$ + 6O_2$$
