B. Hypothesis, observation, testing, predictions, theory
C. Testing, observation, hypothesis, theory, predictions
D. Theory, hypothesis, observation, testing, predictions
Correct Answer: A
Rationale: The best answer is A because the scientific method begins with observation, followed by
forming a hypothesis, making predictions, testing, and developing a theory.

of cellulose?
A. Protista
B. Fungi
C. Plantae [CORRECT]
D. Animalia
Correct Answer: C
Rationale: The best answer is C because the kingdom Plantae includes multicellular, photosynthetic
organisms with cell walls made of cellulose.
Q7: Which kingdom includes multicellular, heterotrophic organisms that lack cell walls?
A. Protista
B. Fungi
C. Plantae
D. Animalia [CORRECT]
Correct Answer: D
Rationale: The best answer is D because the kingdom Animalia includes multicellular, heterotrophic
organisms that lack cell walls.
, Q8: What is the correct order of the eight major taxonomic classifications from broadest to most
specific?
A. Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species [CORRECT]
B. Kingdom, Domain, Phylum, Class, Order, Family, Genus, Species
C. Domain, Phylum, Kingdom, Class, Order, Family, Genus, Species
D. Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain
Correct Answer: A
Rationale: The best answer is A because the correct order from broadest to most specific is Domain,
Kingdom, Phylum, Class, Order, Family, Genus, Species.
Q9: Who created the binomial system of taxonomic classification?
A. Charles Darwin
B. Carolus Linnaeus [CORRECT]
C. Gregor Mendel
D. Louis Pasteur
Correct Answer: B
Rationale: The best answer is B because Carolus Linnaeus created the binomial system of classification,
using genus and species names.
Q10: Which of the following is a characteristic of life that involves maintaining a stable internal
environment?
A. Evolution
B. Homeostasis [CORRECT]
C. Reproduction
D. Metabolism
Correct Answer: B
Rationale: The best answer is B because homeostasis is the ability of an organism to maintain a stable
internal environment.
Q11: Which of the following is a characteristic of life that involves changes in populations over time?
A. Evolution [CORRECT]
B. Homeostasis
C. Reproduction
D. Metabolism
Correct Answer: A
Rationale: The best answer is A because evolution is the change in the genetic makeup of populations
over time.
Q12: Which of the following is the smallest unit of life?
