1. Which characteristic is common to all living organisms?
x x x x x x x
A. Ability to move voluntarily x x x
B. Presence of a nucleus x x x
C. Ability to reproduce x x
D. Presence of chloroplasts x x
Answer: C. Ability to reproduce x x x x
Rationale: All living organisms share fundamental characteristics, including repr
x x x x x x x x
oduction, metabolism, growth, and response to stimuli. While not all organisms ha
x x x x x x x x x x x x
ve a nucleus (prokaryotes lack one) or chloroplasts, reproduction is universal.
x x x x x x x x x x x
2. Which level of biological organization is correctly arranged from simplest to
x x x x x x x x x x
most complex?
x x
A. Organ → Cell → Tissue → Organ System
x x x x x x x
B. Cell → Tissue → Organ → Organ System
x x x x x x x
C. Tissue → Cell → Organ → Organ System
x x x x x x x
D. Organism → Organ System → Organ → Tissue x x x x x x x
Answer: B. Cell → Tissue → Organ → Organ System
x x x x x x x x x
Rationale: Biological organization progresses from simple to complex: cells form
x x x x x x x x x
tissues, tissues form organs, organs work in organ systems, and organ systems fu
x x x x x x x x x x x x x
nction in organisms.
x x x
3. Homeostasis is best described as: x x x x
A. The ability to produce energy
x x x x
B. Maintaining a stable internal environment x x x x
C. The process of evolution
x x x
D. The creation of new species
x x x x
Answer: B. Maintaining a stable internal environment
x x x x x x
Rationale: Homeostasis is the regulation of internal conditions such as temperatu
x x x x x x x x x x
re, pH, and fluid balance, despite changes in the external environment.
x x x x x x x x x x x
,4. The primary molecule for storing genetic information is:
x x A x x x x
A. Carbohydrates
B. Lipids
C. DNA
D. Proteins
Answer: C. DNA x x
Rationale: DNA (deoxyribonucleic acid) contains hereditary information that gui
x x x x x x x x
des growth, development, and reproduction in all living organisms.
x x x x x x x x x
5. Evolution explains: x
A. How individual organisms adapt during their lifetime
x x x x x x
B. How populations change over generations
x x x x
C. The immediate response of an organism to stimuli
x x x x x x x
D. The process of cellular respiration
x x x x
Answer: B. How populations change over generations
x x x x x x
Rationale: Evolution is the process bywhich populations of organisms change genetic
x x x x x x x x x x
ally over time due to natural selection, mutation, and other mechanisms.
x x x x x x x x x x x
6. Which of the following is a prokaryotic organism?
x x x x x x x
A. Amoeba
B. Bacterium
C. Algae
D. Yeast
Answer: B. Bacterium x x
Rationale: Prokaryotic cells lack a nucleus and membrane-
x x x x x x x
bound organelles, which is characteristic of bacteria. Amoebas, algae, and yeast ar e
x x x x x x x x x x x x
eukaryotic.
x
7. Which of the following best illustrates an emergent property?
x x x x x x x x
A. Chlorophyll in plants absorbing sunlight x x x x
B. Water molecules forming liquid
x x x
, C. Heart pumping blood as part of the circulatory system
x x x x x x x x
D. DNA replication x
Answer: C. Heart pumping blood as part of the circulatory system
x x x x x x x x x x
Rationale: Emergent properties arise when individual components interact to form a
x x x x x x x x x x
system with new functions. The heart alone cannot pump blood until organized i
x x x x x x x x x x x x x
nto a system.
x x x
8. Which scientific method step involves forming a testable statement?
x x x x x x x x
A. Observation
B. Hypothesis
C. Experiment
D. Conclusion
Answer: B. Hypothesis x x
Rationale: A hypothesis is a testable statement predicting a relationship between varia bles,
x x x x x x A x x x x x
based on prior observations.
x x x x
9. Which of these is an example of adaptation?
x x x x x x x
A. A plant wilting due to lack of water
x x x x x x x
B. Polar bears having thick fur in Arctic regions
x x x x x x x
C. A human learning to swim
x x x x
D. Bacteria dying from antibiotics x x x
Answer: B. Polar bears having thick fur in Arctic regions
x x x x x x x x x
Rationale: Adaptations are inherited traits that increase survival and reproduction in
x x x x x x x x x x
specific environments.
x x
10. The process bywhich organisms maintain internal conditions despite external
x x x x x x x x
changes is called:
x x x
A. Photosynthesis
B. Homeostasis
C. Metabolism
D. Evolution
