Question 1

Which of the following is NOT a property common to all living things?

Accepted Answer

Ability to photosynthesize

Question 2

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

Accepted Answer

Question 3

In a controlled experiment testing the effect of a new fertilizer on plant growth, which of the following is the dependent variable?

Accepted Answer

The growth of the plants measured in height

Question 4

Which of the following statements about scientific theories is correct?

Accepted Answer

A scientific theory is broad in scope and supported by a large body of evidence

Question 5

Which domain includes organisms with simple cells that lack a nucleus?

Accepted Answer

Domain Bacteria

Question 6

A scientist observes that red pandas and raccoons share physical similarities. She hypothesizes they are closely related. Which type of data would best test this hypothesis?

Accepted Answer

Comparing their DNA sequences

Question 7

Why are DNA sequence comparisons considered observational data rather than experimental data?

Accepted Answer

Because DNA sequences are observed and recorded without manipulation

Question 8

Which of the following best explains why humans are considered agents of both artificial and natural selection?

Accepted Answer

Humans intentionally breed organisms for desired traits and also unintentionally alter environments, affecting natural selection

Question 9

Which of the following is an example of the relationship between structure and function at the molecular level?

Accepted Answer

The shape of hemoglobin allows it to transport oxygen in blood

Question 10

In the flow of energy through an ecosystem, which of the following correctly describes the path of energy?

Accepted Answer

Energy enters as sunlight, is converted to chemical energy by producers, passed to consumers, and exits as heat

Question 11

Which of the following best describes the difference between a hypothesis and a scientific theory?

Accepted Answer

A hypothesis is a specific, testable statement, while a theory is a broad explanation supported by much evidence

Question 12

Which of the following levels of biological organization includes all the others listed: cell, molecule, organ, tissue?

Accepted Answer

Organ

Question 13

A researcher wants to test the effect of temperature on enzyme activity. She keeps all other variables constant except temperature. What is the purpose of this experimental design?

Accepted Answer

To ensure that any observed effect is due to temperature alone

Question 14

Which of the following is an example of an emergent property at the tissue level?

Accepted Answer

A group of muscle cells contracting together to produce movement

Question 15

Which of the following best describes the flow of information in a cell?

Accepted Answer

DNA $$\rightarrow$$ RNA $$\rightarrow$$ Protein

Question 16

A patient with diabetes has high blood glucose levels. Which of the following best explains how the body normally regulates blood glucose?

Accepted Answer

The pancreas releases insulin, which signals body cells to take up glucose, lowering blood glucose levels

Question 17

Which of the following is a real-world example of artificial selection?

Accepted Answer

Farmers breeding cows that produce more milk

Question 18

Which of the following best illustrates the concept of systems biology?

Accepted Answer

Modeling the interactions among all genes, proteins, and metabolic pathways in a cell

Question 19

Which of the following is true about the cycling of matter in an ecosystem?

Accepted Answer

Matter cycles between the atmosphere, soil, producers, consumers, and decomposers

Question 20

Which of the following is an example of evolutionary adaptation?

Accepted Answer

A red panda's wrist bone allowing it to grasp bamboo
