Answer: C – Population
Rationale: A population consists of members of the same species living in a defined area. Communities
include multiple species.
2. Chloroplasts convert sunlight into:
A) Energy of motion
B) Carbon dioxide and water
C) Potential energy in chemical bonds
D) Oxygen
E) Kinetic energy
Answer: C
Rationale: Photosynthesis stores light energy as chemical energy in glucose bonds.
3. Main energy source for producers:
Answer: A – Light energy
Rationale: Autotrophs capture solar energy via photosynthesis.
4. Cells with DNA not enclosed in a nucleus:
Answer: C – Archaea
Rationale: Archaea are prokaryotes lacking a membrane-bound nucleus.
5. Studying DNA structure to understand inheritance illustrates:
Answer: C – Reductionism
Rationale: Reductionism explains complex systems by analyzing smaller components.
6. Increasing labor contractions represent:
Answer: B – Positive feedback
Rationale: Positive feedback amplifies the original stimulus.
7. Blood glucose regulation is:
Answer: C – Negative feedback
Rationale: The response counteracts deviation from a set point.
8. Naming and classifying organisms:
Answer: C – Taxonomy
Rationale: Taxonomy organizes life into hierarchical categories.

9. Shared feature of prokaryotes and eukaryotes:
Answer: C – Ribosomes
Rationale: All cells possess ribosomes for protein synthesis.
10. Two prokaryotic domains:
Answer: E – Bacteria and Archaea
11. Best solution to global warming:
Answer: D – Limit fossil fuel use and deforestation
Rationale: Addresses root causes of increased greenhouse gases.
12. Single-celled organism in hot vent without nucleus:
Answer: B – Archaea
13. Filamentous decomposer with cell wall, no chloroplasts:
Answer: E – Domain Eukarya, Kingdom Fungi
Rationale: Fungi absorb nutrients and lack chloroplasts.
14. Evidence for common ancestry:
Answer: B – Near universality of genetic code
Rationale: Shared genetic code indicates shared evolutionary origin.
15. Natural selection requires and results in:
Answer: E – Genetic variation, differential success, descent with modification
16. Darwin’s adaptation concept:
Answer: D – Inheritable traits enhancing survival and reproduction

17. Greatest evolutionary success:
Answer: B – Dies early but leaves 10 reproducing offspring
Rationale: Fitness is measured by reproductive success.
18. Eliminating tall individuals over time would:
Answer: B – Gradually decline average height
19. Whale evolution explained by:
Answer: D – Natural selection
20. Major difference between kingdom and domain:
Answer: B – All eukarya belong to one domain
21. Reaction to Origin of Species:
Answer: C – Widely discussed and disseminated
22. Darwin’s originality:
Answer: D – Proposed mechanism for evolution
23. Darwin’s finches demonstrate:
Answer: C – Adaptive radiation
24. Least likely classification to change:
Answer: E – Species
Rationale: Species designation is more specific and stable.
