Question 1

Which of the following is NOT one of the seven properties common to all life as described in the study materials?

Accepted Answer

Ability to move independently

Question 2

A scientist observes that a certain species of plant grows taller when exposed to more sunlight. She hypothesizes that increased sunlight causes increased growth. Which of the following best identifies the independent and dependent variables in her experiment?

Accepted Answer

Independent variable: amount of sunlight; Dependent variable: plant height

Question 3

Which of the following best explains why DNA sequence comparisons are considered observational data rather than experimental data?

Accepted Answer

Because scientists do not manipulate DNA sequences but instead observe and compare existing sequences

Question 4

In a controlled experiment testing the effect of a new fertilizer on plant growth, why is it important to match factors such as soil type, water, and light between the control and experimental groups?

Accepted Answer

To ensure that differences in plant growth are due to the fertilizer and not other variables

Question 5

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 6

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

Accepted Answer

New properties arise at each level of organization due to the arrangement and interactions of parts

Question 7

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

Accepted Answer

Molecule, cell, tissue, organ, organism

Question 8

Which domain of life includes organisms with complex cells containing a nucleus?

Accepted Answer

Domain Eukarya

Question 9

A researcher is studying the effect of a new drug on blood pressure in humans. She randomly assigns participants to receive either the drug or a placebo. What is the main purpose of including a placebo group in this experiment?

Accepted Answer

To serve as a control group for comparison with the experimental group

Question 10

Which of the following best illustrates the relationship between structure and function in biology?

Accepted Answer

The long extensions of nerve cells enable them to transmit impulses over long distances

Question 11

Which of the following is an example of artificial selection?

Accepted Answer

Breeding dogs for specific traits such as size or coat color

Question 12

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

Accepted Answer

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

Question 13

Which of the following is a correct statement about the cycling of matter in ecosystems?

Accepted Answer

Matter cycles from the atmosphere and soil, through producers, consumers, and decomposers, and back to the environment

Question 14

A biologist is using systems biology to study the interactions within a cell. Which of the following best describes this approach?

Accepted Answer

Modeling the behavior of the cell by analyzing the interactions among its parts

Question 15

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

Accepted Answer

The ability of muscle tissue to contract, which individual muscle cells alone cannot achieve

Question 16

Which of the following best explains how DNA determines an organism’s structures and functions?

Accepted Answer

DNA provides the blueprint for proteins, which carry out most cellular activities

Question 17

Which of the following is a real-world example of evolutionary adaptation?

Accepted Answer

The camouflage of red pandas among red mosses and white lichens

Question 18

Which of the following best distinguishes a scientific hypothesis from a scientific theory?

Accepted Answer

A hypothesis is a testable explanation for a specific observation, while a theory is broad in scope and supported by extensive evidence

Question 19

Which of the following is an example of how humans act as agents of both artificial and natural selection?

Accepted Answer

By selectively breeding crops for higher yield (artificial selection) and unintentionally favoring pest-resistant weeds through herbicide use (natural selection)

Question 20

Which of the following equations best represents the flow of energy in an ecosystem as described in the study materials?

Accepted Answer

$$	ext{Sunlight} ightarrow 	ext{Producers} ightarrow 	ext{Consumers} ightarrow 	ext{Heat}$$
