Question 2

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

Accepted Answer

The exposure to sunlight.

Question 3

Which of the following is NOT one of the four unifying themes of biology as described in the study materials?

Accepted Answer

Cellular respiration

Question 4

In a controlled experiment testing the effect of fertilizer on plant growth, which group serves as the control?

Accepted Answer

The group that receives no fertilizer.

Question 5

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

Accepted Answer

The structure of a biological component often gives insight into its function.

Question 6

Which of the following best illustrates the concept of reductionism in biology?

Accepted Answer

Breaking down a complex organism into its cellular components for study.

Question 7

A mouse population living on dark soil has evolved dark fur coloration. According to the study materials, what is the most likely explanation for this adaptation?

Accepted Answer

Dark fur coloration provides camouflage, reducing predation and increasing survival.

Question 8

Which of the following is an example of qualitative data?

Accepted Answer

The color of flowers observed in a field is red, yellow, and blue.

Question 9

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

Accepted Answer

The process of converting information from a gene to a cellular product, often a protein.

Question 10

Which of the following is a correct example of inductive reasoning in biology?

Accepted Answer

If all observed cells are made of membranes, then all cells must have membranes.

Question 11

Which of the following statements about scientific theories is TRUE?

Accepted Answer

A scientific theory is broader in scope than a hypothesis and supported by a large body of evidence.

Question 12

Which of the following best describes the flow of energy in an ecosystem?

Accepted Answer

Energy flows from the sun to producers, then to consumers, and is eventually lost as heat.

Question 13

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

Accepted Answer

If a supernatural force causes plants to grow, then growth will occur regardless of conditions.

Question 14

Which of the following best explains why antibiotic resistance is an example of evolution by natural selection?

Accepted Answer

Antibiotic resistance arises because resistant bacteria survive and reproduce more successfully in the presence of antibiotics.

Question 15

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

Accepted Answer

Organelles, cells, tissues, organs, organisms, populations, communities, ecosystems, biosphere

Question 16

Which of the following best describes the role of DNA in cells?

Accepted Answer

DNA contains the genetic instructions for building and maintaining the cell.

Question 17

A researcher observes that all the plants in her experiment grew taller when exposed to blue light. She concludes that blue light increases plant growth. What type of reasoning is she using?

Accepted Answer

Inductive reasoning

Question 18

Which of the following is a characteristic shared by all cells?

Accepted Answer

They are surrounded by a membrane.

Question 19

Which of the following best describes the dependent variable in an experiment?

Accepted Answer

The variable that is measured as the outcome of the experiment.

Question 20

Which of the following is an example of energy processing in living organisms?

Accepted Answer

A plant converting sunlight into chemical energy through photosynthesis.
