Question 1

Which of the following best describes an emergent property in biological systems?

Accepted Answer

Question 2

Which of the following is NOT one of the five unifying themes of biology?

Accepted Answer

Reproduction

Question 3

A scientist observes that all cells contain DNA. She then hypothesizes that DNA is necessary for life. Which type of reasoning is she using?

Accepted Answer

Inductive reasoning

Question 4

Which of the following statements about negative feedback in biological systems is correct?

Accepted Answer

Negative feedback reduces the initial stimulus, helping maintain homeostasis.

Question 5

Which domain of life includes organisms that absorb nutrients from their environment and are mostly multicellular?

Accepted Answer

Domain Eukarya

Question 6

Which of the following best illustrates the concept of 'descent with modification' as described by Darwin?

Accepted Answer

Species show evidence of change over time, with traits inherited from common ancestors being modified.

Question 7

A researcher wants to test the hypothesis that a certain plant grows faster in sunlight than in shade. Which requirement must this hypothesis meet to be considered scientific?

Accepted Answer

It must be testable and falsifiable.

Question 8

Which of the following is an example of a producer in an ecosystem?

Accepted Answer

A tree performing photosynthesis.

Question 9

Which hierarchical level of biological organization is correctly ordered from smallest to largest?

Accepted Answer

Molecule, organelle, cell, tissue

Question 10

Which of the following is a correct statement about the relationship between science and technology?

Accepted Answer

Science and technology are interdependent; scientific discoveries often lead to technological inventions, and technology can enable new scientific discoveries.

Question 11

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

Accepted Answer

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

Question 12

Which of the following is a real-world example of positive feedback in biological systems?

Accepted Answer

Blood clotting, where the process accelerates until completion.

Question 13

Which of the following is a correct application of deductive reasoning in scientific inquiry?

Accepted Answer

Using a general principle that all living things contain cells to predict that a newly discovered organism will have cells.

Question 14

Which of the following is the correct LaTeX representation for the central dogma of molecular biology?

Accepted Answer

$$DNA \rightarrow RNA \rightarrow Protein$$

Question 15

Which of the following best explains why 'life' is considered an emergent property at the cellular level?

Accepted Answer

Because the interaction of organelles and molecules within a cell gives rise to properties not found in the individual components.

Question 16

Which of the following is a correct statement about taxonomy?

Accepted Answer

Taxonomy is the branch of biology that names and classifies species into groups of increasing breadth.

Question 17

A scientist is studying the effect of a new drug on blood glucose levels. She measures glucose levels before and after administering the drug. Which type of data is she collecting?

Accepted Answer

Quantitative data

Question 18

Which of the following is a plausible misconception about evolution?

Accepted Answer

Evolution is a process that only occurred in the past and does not happen today.

Question 19

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

Accepted Answer

Biosphere, ecosystem, community, population, organism, organ system, organ, tissue, cell, organelle, molecule

Question 20

Which of the following is a correct statement about the role of diverse viewpoints in science?

Accepted Answer

Science benefits from diverse views from different racial and ethnic groups, and from both women and men.
