Question 1

Which of the following is NOT considered a property of life?

Accepted Answer

Question 2

A scientist observes that a certain plant bends toward light. Which property of life does this illustrate?

Accepted Answer

Response to the environment

Question 3

Which of the following correctly matches the domain with its description?

Accepted Answer

Domain Eukarya: includes protists, fungi, plants, and animals

Question 4

Emergent properties are best described as:

Accepted Answer

Properties that arise from the arrangement and interaction of parts within a system

Question 5

In a controlled experiment, the independent variable is:

Accepted Answer

The factor that is manipulated by the researcher

Question 6

A clinical trial tests a new medication for diabetes. Researchers ensure that both the control and experimental groups have similar age, sex, and health status. What is the purpose of this design?

Accepted Answer

To minimize confounding variables and isolate the effect of the medication

Question 7

Comparisons of DNA sequences to determine evolutionary relationships are considered observational data because:

Accepted Answer

They are based on direct observation without experimental manipulation

Question 8

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

Accepted Answer

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

Question 9

Which of the following is an example of artificial selection?

Accepted Answer

Humans breeding dogs for specific traits such as size or temperament

Question 10

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

Accepted Answer

The structure of a biological component determines its function

Question 11

Which of the following best illustrates the concept of emergent properties?

Accepted Answer

A functioning heart made up of many muscle cells working together

Question 12

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

Accepted Answer

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

Question 13

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

Accepted Answer

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

Question 14

Which of the following best explains how photosynthesis transforms energy and matter?

Accepted Answer

Photosynthesis converts sunlight into chemical energy stored in glucose

Question 15

A researcher wants to test the hypothesis that a new fertilizer increases plant growth. Which of the following would be the best experimental design?

Accepted Answer

Apply the fertilizer to half the plants (experimental group) and leave the other half untreated (control group), then compare growth

Question 16

Which of the following is an example of information flow in biological systems?

Accepted Answer

The transmission of genetic instructions from DNA to RNA to protein

Question 17

Which of the following best describes the relationship between science and technology?

Accepted Answer

Science aims to understand natural phenomena, while technology applies scientific knowledge for specific purposes

Question 18

A box of bicycle parts cannot be ridden, but when assembled correctly, the bicycle can be used for transportation. In biology, this is an analogy for:

Accepted Answer

Emergent properties resulting from the interactions of system components

Question 19

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

Accepted Answer

Molecule, cell, tissue, organ

Question 20

Which of the following best explains why hypothesis testing is at the core of the scientific process?

Accepted Answer

It provides a structured way to test explanations and build evidence-based understanding
