1. Which of the following is NOT one of the seven widely accepted
characteristics of living organisms?
A) Order
B) Evolutionary Adaptation
C) Homeostasis
D) Reproduction
Correct Answer: Homeostasis
Rationale: The seven characteristics are Order, Evolutionary Adaptation,
Regulation, Energy Processing, Growth and Development, Response to the
Environment, and Reproduction. While homeostasis is related to regulation, it
is not listed as one of the seven core characteristics.
2. A single living member of a population is best described as a(n):
A) Organism
B) Community
C) Ecosystem
D) Biosphere
Correct Answer: Organism
Rationale: An organism is an individual living member of a population. A
population is a group of one species, a community includes multiple
populations, an ecosystem includes living and non-living components, and
the biosphere is the global ecosystem.
,3. A group of one particular species living within defined boundaries best
describes a(n):
A) Organism
B) Community
C) Population
D) Ecosystem
Correct Answer: Population
Rationale: A population consists of a group of one particular species living
within defined boundaries of a community. Communities include multiple
populations, and ecosystems include both living and non-living components.
4. A system of living and non-living things in a region best describes a(n):
A) Population
B) Community
C) Organism
D) Ecosystem
Correct Answer: Ecosystem
Rationale: An ecosystem is a system of living and non-living things in a
region. It includes the biological community and its physical environment.
5. The broadest level of biological organization is the:
A) Community
B) Ecosystem
C) Biosphere
, D) Population
Correct Answer: Biosphere
Rationale: The biosphere is the broadest level of biological organization,
encompassing all ecosystems on Earth. It includes all regions of the planet
where living organisms exist.
6. What are the three domains that comprise the Linnaean Classification
system?
A) Animalia, Plantae, Fungi
B) Protista, Archaea, Eukarya
C) Archaea, Eubacteria, Eukarya
D) Eubacteria, Protista, Animalia
Correct Answer: Archaea, Eubacteria, Eukarya
Rationale: The three domains are Archaea, Eubacteria (Bacteria), and
Eukarya. The kingdoms (Animalia, Plantae, Fungi, Protista) fall within the
Eukarya domain.
7. Which domain contains organisms that are often extremophiles?
A) Eukarya
B) Eubacteria
C) Archaea
D) Protista
Correct Answer: Archaea
