Question 1

Which of the following best illustrates the concept of emergent properties in biological systems?

Accepted Answer

Photosynthesis occurs only in intact chloroplasts, not in a test tube containing isolated chlorophyll.

Question 2

Which of the following is NOT a unifying theme of biology?

Accepted Answer

Randomness

Question 3

A scientist is studying the effect of temperature on the rate of photosynthesis in plants. Which is the independent variable in this experiment?

Accepted Answer

The temperature at which the plants are kept

Question 4

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

Accepted Answer

Structure determines function at all levels of biological organization.

Question 5

Which of the following is a correct application of the scientific method?

Accepted Answer

Forming a hypothesis after collecting data and then testing it with an experiment.

Question 6

Which domain of life contains organisms that are all eukaryotic?

Accepted Answer

Eukarya

Question 7

In the mouse camouflage experiment, what was the dependent variable?

Accepted Answer

The percentage of attacked models

Question 8

Which of the following best explains why natural selection is considered a theory?

Accepted Answer

It is a broad explanation supported by a large body of evidence and can generate new hypotheses.

Question 9

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

Accepted Answer

Insulin signaling reduces blood glucose levels after a meal.

Question 10

Which equation correctly represents the flow of energy in an ecosystem?

Accepted Answer

$$	ext{Light energy} ightarrow 	ext{Chemical energy} ightarrow 	ext{Heat}$$

Question 11

Which reasoning method is used when generalizations are made from many specific observations?

Accepted Answer

Inductive reasoning

Question 12

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

Accepted Answer

DNA is transcribed into mRNA, which is then translated into a protein.

Question 13

Which of the following is a correct representation of the universal genetic code translation?

Accepted Answer

$$	ext{DNA} \xrightarrow{	ext{transcription}} 	ext{mRNA} \xrightarrow{	ext{translation}} 	ext{Protein}$$

Question 14

Which of the following best explains how evolution accounts for both the unity and diversity of life?

Accepted Answer

Descent with modification leads to shared traits (unity) and adaptations to different environments (diversity).

Question 15

Which of the following is NOT a characteristic shared by all cells?

Accepted Answer

Have membrane-bound organelles

Question 16

Which of the following is an example of a controlled experiment?

Accepted Answer

Testing the effect of a drug by giving it to one group and a placebo to another group.

Question 17

Which of the following is a correct hierarchical order from smallest to largest in biological organization?

Accepted Answer

Molecule $$\rightarrow$$ Organelle $$\rightarrow$$ Cell $$\rightarrow$$ Tissue $$\rightarrow$$ Organ $$\rightarrow$$ Organism $$\rightarrow$$ Population $$\rightarrow$$ Community $$\rightarrow$$ Ecosystem $$\rightarrow$$ Biosphere

Question 18

Which of the following is a plausible outcome of increased atmospheric $$\mathrm{CO}_2$$ due to fossil fuel burning?

Accepted Answer

Directional change in climate lasting over 30 years (climate change)

Question 19

Which of the following best describes the difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells have membrane-bound organelles; prokaryotic cells do not.
