1. Whichcharacteristic is commonto allliving organisms?
i i i i i i ii
A. Ability to move voluntarily ii ii i
B. Presence of a nucleus ii ii ii
C. Ability to reproduce ii i
D. Presence of chloroplasts ii ii
Answer:C. Ability to reproduce i i ii ii
Rationale:All living organisms share fundamental characteristics, including repr
i ii i i ii ii ii ii ii
oduction, metabolism, growth, and responseto stimuli. While not all organisms ha
ii ii ii ii ii i ii i i ii i ii ii
ve a nucleus (prokaryotes lack one) or chloroplasts, reproduction is universal.

2. Whichlevel ofbiological organization is correctly arranged fromsimplest to
i ii i ii ii ii i ii i ii
most complex?
ii ii
A. Organ → Cell → Tissue → Organ System ii ii ii ii i i ii
B. Cell → Tissue→ Organ → Organ System
ii i i ii ii i ii
C. Tissue→ Cell → Organ → Organ System i ii ii ii ii i ii
D. Organism → Organ System→ Organ → Tissue ii i ii i ii ii ii
Answer:B. Cell → Tissue → Organ → Organ System
i ii ii i i ii ii i ii
Rationale: Biological organization progresses from simple to complex: cells form
i i ii i i ii i ii ii
tissues, tissues form organs, organs work in organ systems, and organ systems fu
ii ii ii ii ii ii ii ii ii ii ii ii ii
nction in organisms.

3. Homeostasis is bestdescribed as: i ii i i
A. Theability to produceenergy
i ii i i
B. Maintaining astable internal environment ii i i ii
C. The process ofevolution
ii ii i
D. The creation of new species
ii ii ii ii
Answer:B. Maintaining astable internal environment
i i ii i i ii
Rationale: Homeostasis is the regulation of internal conditions such as temperatu
i ii ii ii i i ii i i ii ii ii
re, pH, and fluid balance, despite changes in the external environment.
ii ii ii ii ii ii ii ii ii ii ii
,4. Theprimary molecule for storing genetic information is:
i ii A i i ii ii
A. Carbohydrates
B. Lipids
C. DNA
D. Proteins
Answer: C. DNA ii ii
Rationale:DNA(deoxyribonucleic acid)contains hereditary information that gui
i i ii i ii ii ii ii
des growth, development, and reproduction in all living organisms.
ii ii ii ii ii ii ii ii i i
5. Evolution explains: ii
A. Howindividual organisms adaptduring their lifetime
i i i i i ii
B. Howpopulations change over generations
i ii i i
C. Theimmediate responseofan organism to stimuli
i ii i i ii ii ii
D. Theprocess ofcellular respiration
i i i ii
Answer:B. Howpopulations change over generations
i i i ii i i
Rationale:Evolution is the process bywhich populations oforganisms change genetic
i ii ii ii i ii ii i ii ii
ally over time due to natural selection, mutation, and other mechanisms.
ii i i ii ii ii ii ii ii ii ii ii
6. Whichofthe following is a prokaryotic organism?
i i i ii ii i ii
A. Amoeba
B. Bacterium
C. Algae
D. Yeast
Answer:B. Bacterium i ii
Rationale:Prokaryotic cells lack a nucleus and membrane-
i i ii ii i ii i
bound organelles, which is characteristic of bacteria. Amoebas,algae, and yeast ar e
ii ii ii ii ii i ii i ii ii ii ii
eukaryotic.

7. Whichofthe following best illustrates anemergent property?
i i i ii i ii i ii
A. Chlorophyllin plants absorbing sunlight i i ii i
B. Watermolecules forming liquid
i i i
, C. Heartpumping blood as part ofthe circulatory system
i ii i i ii i ii ii
D. DNA replication ii
Answer:C. Heartpumping blood as part of the circulatory system
i i i ii i ii i i ii ii
Rationale: Emergent properties arise when individual components interact to form a
i i i ii ii i i i ii i ii
system with new functions. The heart alone cannot pump blood until organized i
ii ii ii ii ii ii ii ii ii ii ii i i ii
nto a system.

8. Whichscientific method step involves forming atestable statement?
i i i i ii i i i
A. Observation
B. Hypothesis
C. Experiment
D. Conclusion
Answer:B. Hypothesis i ii
Rationale:Ahypothesis is atestable statement predicting a relationship between varia bles,
i i i ii i ii A ii i i i ii ii
based on prior observations.
i i ii ii ii
9. Whichof these is an example ofadaptation?
i i i ii ii ii i
A. Aplant wilting due to lack ofwater
i i i i i i ii i
B. Polarbears having thick fur in Arctic regions
i i ii ii ii ii ii
C. Ahumanlearning to swim
i i ii ii
D. Bacteria dying fromantibiotics ii ii i
Answer:B. Polarbears having thick fur in Arctic regions
i i i i ii ii i ii ii
Rationale:Adaptations areinherited traits that increase survival and reproduction in
i i i ii ii ii ii ii ii ii
specific environments.

10. The process bywhich organisms maintain internal conditions despite external
i i i ii i i ii ii i
changes is called:
ii ii ii
A. Photosynthesis
B. Homeostasis
C. Metabolism
D. Evolution
