1) Which Of The Following Is Not Related To The Five Fundamental Characteristics Of
Life?
A) A Bacterial Cell Divides To Produce Two Cells.
B) Sugars Are Transported On Carrier Proteins Into Cells Across The Plasma Membrane.
C) Sugars Are Broken Down Inside Cells To Produce Energy.
D) The Gene That Specifies Skin Color In Frogs Is Expressed During Its Development
From A Tadpole Into An Adult Frog.
E) Giraffes Have Longer Necks So That They Can Reach Food Sources Unavailable To
Other Animals.
ANSWER: E
The Five Fundamental Characteristics Of Life Are Growth, Reproduction, Response To
Stimuli, Energy Use, And Adaptation/Evolution. While Options A To D Are Directly
Related To These Characteristics, E Refers To A Physical Trait (Longer Necks In
Giraffes) That Is More Related To Evolutionary Adaptation, Not Directly To The Basic
Characteristics Of Life Itself. Option E Pertains To Natural Selection But Is Not One Of
The Five Core Characteristics Of Life.

2) Which Of The Following Statements Best Describes A Characteristic That May Be
Associated With Both Living Organisms And Nonliving Matter?
A) Reproduction By Passing On Genetic Information To Future Generations.
B) Composed Of Cells.
C) Capable Of Evolution.
D) Able To Produce Heat As A Byproduct Of Chemical Reactions.
ANSWER: D
Both Living Organisms And Nonliving Matter Can Produce Heat As A Byproduct Of
Chemical Reactions, Particularly In Processes Like Combustion Or Metabolism. This
Heat Production Is Not Exclusive To Life. In Contrast, A, B, And C Are Characteristics
Exclusive To Living Organisms.

3) Which Of The Following Statements Is An Inaccurate Example Of How The Living
Organism In The Scenario Exemplifies A Characteristic Feature Of Living Organisms?
,A) Photosynthetic Bacteria Meet The Energy Requirement, As They Are Able To
Convert Energy From Sunlight Into The Chemical Energy They Store In Sugars.
B) As Humans, We Meet The Cell Requirement Because Even Though We Made Of
Tissues And Organs, All Those Components Are Made Of Specialized Types Of Cells.
C) English Bulldogs Would Meet Both The Information And Ability To Replicate
Requirements Because When They Have A Litter Of Puppies, We Would Expect The
Progeny To Be English Bulldogs Due To Their DNA From The Parents.
D) Monarch Butterflies Meet The Evolution Requirement Because Each Of Them Will
Look Different As Adults (Butterflies) Than They Do As Juveniles (Caterpillars) Which
Demonstrate Their Ability To Change Over Time.
E) All Of The Statements Are Proper Example Of How That Organism Exemplifies
Particular Characteristics Of Life.
ANSWER: D
Option D Is Incorrect Because The Statement About Monarch Butterflies Does Not
Accurately Describe The Characteristic Of Evolution. Evolution Is A Long-Term Process
That Occurs Over Generations, Not Just The Individual Development From Larvae To
Adult (Metamorphosis). The Change Observed In Monarchs Is Developmental, Not
Evolutionary, Which Takes Place Over Many Generations.

B) In Order To Grow, Cells Need To Be Supplied With Oxygen
C) Spontaneous Generation Can Only Pccur If Nutrient Broth Is Left Open To The
Environment
D) Sterilizing Nutrient Broth Prevents Spontaneous Generation
E) Preexisting Cells Present In The Air Can Grow In Sterilized Nutrient Broth
ANSWER: E
Pasteur's Experiments Showed That Preexisting Cells (From The Air) Could Grow In
Sterilized Nutrient Broth When It Was Exposed To Air. However, The Swan-Neck Flask
Design Prevented Airborne Particles (Cells) From Entering And Thus Prevented The
Growth Of Microorganisms, Disproving Spontaneous Generation.

Nutrient-Rich Broth, Rather Than Boiled It, What Would Have Been The Likely Outcome
Of His Experiment? Cells Would ______.
A) Not Have Appeared In Either Flask
B) Have Appeared In Both Flasks
C) Have Appeared In The Swan-Neck But Not The Straight-Neck Flask
D) Have Appeared In The Straight-Neck But Not The Swan-Neck Flask
ANSWER: B
If Pasteur Had Just Warmed The Broth Rather Than Boiling It, Microorganisms From
The Air Could Have Been Introduced Into The Broth In Both Flasks, Since The Boiling
Process Was What Sterilized The Broth. This Would Have Resulted In The Appearance
Of Cells In Both Flasks.

B) Apparently Occurred At Least Once-When Life On Earth Began
C) Occurs Every Time A New Species Evolves From A Preexisting Species
D) Addresses The Formation Of New Cells From Existing Cells
,ANSWER: B
Spontaneous Generation Refers To The Idea That Life Could Arise From Nonliving
Matter, Which Was Suggested To Have Happened When Life First Began On Earth.
However, Pasteur’s Experiments Disproved Spontaneous Generation In The Context Of
Microorganisms.

Results Have Been If Pasteur’s Swan-Neck Experiment Hypothesis Were Incorrect?
A) Cells Would Not Have Appeared In Either Flask.
B) Cells Would Have Appeared In Both Flasks.
C) Cells Would Have Appeared In The Swan-Neck But Not The Straight-Neck Flask.
D) Cells Would Have Appeared In The Staright-Neck But Not The Swan-Neck Flask
ANSWER: B
If Pasteur’s Hypothesis Were Incorrect, And Spontaneous Generation Were Indeed
Possible, Then Cells Would Have Appeared In Both The Straight-Neck And Swan-Neck
Flasks. The Swan-Neck Design Prevented Cell Entry, Which Supported His Conclusion
That Life Did Not Arise Spontaneously.

8) Algae In The Genus Caulerpa Typically Grow To A Length Of Over Half A Meter And
Have Structure Similar To Stems, Leaves, And Roots. Reproduction Occurs When Adults
Produce Sperm And Eggs That Fuse To Form Offspring. Each Adult Caulerpa Consists Of
Just A Single Cell, However. Which Of The Following Statements Is True?
A) Caulerpa Violate The Pattern Component Of The Cell Theory That All Organisms
Consist Of Cells.
B) Caulerpa Violate The Process Component Of The Cell Theory That All Cells Come
From Preexisting Cells.
C) Caulerpa Violate Both The Pattern And Process Components Of The Cell Theory.
D) The Existence Of Caulerpa Is Consistent With The Cell Theory.
ANSWER: D
Despite Being A Large, Multicellular-Like Organism, Caulerpa Is A Single Cell. The
Cell Theory Does Not Require Each Organism To Be Made Of Many Cells, But It States
That All Life Is Made Up Of Cells Or Is A Product Of A Single Cell (Like Caulerpa).
Thus, Caulerpa Is Consistent With The Cell Theory.
