,Chapter 1: The Science Of Life
1. Which Characteristic Is Common To All Living Organisms?
A. Ability To Move Voluntarily
B. Presence Of A Nucleus
C. Ability To Reproduce
D. Presence Of Chloroplasts
ANS: C. Ability To Reproduce
Rationale: All Living Organisms Share Fundamental Characteristics, Including
Repr Oduction, Metabolism, Growth, And Response To Stimuli. While Not All
Organisms Ha Ve A Nucleus (Prokaryotes Lack One) Or Chloroplasts,
Reproduction Is Universal.
2. Which Level Of Biological Organization Is Correctly Arranged From
Simplest To Most Complex?
A. Organ → Cell → Tissue → Organ System
B. Cell → Tissue → Organ → Organ System
C. Tissue → Cell → Organ → Organ System
D. Organism → Organ System → Organ → Tissue
ANS: B. Cell → Tissue → Organ → Organ System
Rationale: Biological Organization Progresses From Simple To Complex: Cells
Form Tissues, Tissues Form Organs, Organs Work In Organ Systems, And Organ
Systems Fu Nction In Organisms.
3. Homeostasis Is Best Described As:
A. The Ability To Produce Energy
B. Maintaining A Stable Internal Environment
C. The Process Of Evolution
D. The Creation Of New Species
ANS: B. Maintaining A Stable Internal Environment
Rationale: Homeostasis Is The Regulation Of Internal Conditions Such As
Temperatu Re, Ph, And Fluid Balance, Despite Changes In The External
Environment.
,4. The Primary Molecule For Storing Genetic Information Is:
A. Carbohydrates
B. Lipids
C. Dna
D. Proteins
ANS: C. Dna
Rationale: Dna (Deoxyribonucleic Acid) Contains Hereditary Information That
Gui Des Growth, Development, And Reproduction In All Living Organisms.
5. Evolution Explains:
A. How Individual Organisms Adapt during Their Lifetime
h
B. How Populations Change Over Generations
C. The Immediate Response Of An Organism To Stimuli
D. The Process Of Cellular Respiration
ANS: B. How Populations Change Over Generations
Rationale: Evolution Is The Process By Which Populations Of Organisms Change
Genetic Ally Over Time Due To Natural Selection, Mutation, And Other Mechanisms.
6. Which Of The Following Is A Prokaryotic Organism?
A. Amoeba
B. Bacterium
C. Algae
D. Yeast
ANS: B. Bacterium
Rationale: Prokaryotic Cells Lack A Nucleus And Membrane-
Bound Organelles, Which Is Characteristic Of Bacteria. Amoebas, Algae, And
Yeast Ar E Eukaryotic.
7. Which Of The Following Best Illustrates An Emergent Property?
A. Chlorophyll In Plants Absorbing Sunlight
B. Water Molecules Forming Liquid
, C. Heart Pumping Blood As Part Of The Circulatory System
D. Dna Replication
ANS: C. Heart Pumping Blood As Part Of The Circulatory System
Rationale: Emergent Properties Arise When Individual Components Interact To
Form A System With New Functions. The Heart Alone Cannot pump Blood Until
h
Organized I Nto A System.
8. which scientific method step involves forming a testable statement?
A. observation
B. hypothesis
C. experiment
D. conclusion
ANS: b. hypothesis
rationale: a hypothesis is a testable statement predicting a relationship between varia
bles, based on prior observations.
9. which of these is an example of adaptation?
A. a plant wilting due to lack of water
h
B. polar bears having thick fur in arctic regions
C. a human learning to swim
D. bacteria dying from antibiotics
ANS: b. polar bears having thick fur in arctic regions
rationale: adaptations are inherited traits that increase survival and reproduction in
specific environments.
10. the process by which organisms maintain internal conditions despite external
changes is called:
A. photosynthesis
B. homeostasis
C. metabolism
D. evolution
