Chapter 01: Introduction To Biology
1. A Scientist Observes That When She Opens The Back Door Of Her House To Let
Her Cat Out, The Songs Of A Certain Species Of Bird Abruptly Change. She Wants
To Follow Up On Her Observations With An Informal Experiment. Which Of The
Following Is The Best Hypothesis For Explaining The Birds’ Song Changes?
(Outcome #Ia) (DOK 2) (Paired Item 1)
A. The Bird Species Switches From Song To Warning Call Whenever It Sees A
Potential Predator.*
B. The Bird Species Has A Variety Of Songs That It Sings, Regardless Of What Is
Happening
In Its Environment.
C. The Scientist Is Mistaken And The Songs Do Not Change.
2. A Scientist Wants To Test The Hypothesis That A Certain Bird Species In Her Back
Yard Changes Its Songs To Warning Calls Whenever It Detects The Presence Of A
Potential Predator. Which Of The Following Most Likely Describes Her Initial
Observations? (Outcome #Ia) (DOK 2) (Paired Item 2)
A. The Scientist Noticed That Whenever She Opened A Door To Her House, She
Heard Birds Beginning To Sing.
B. Each Time The Scientist Let Her Cat Outside, The Birds Abruptly Changed Their
Songs.*
C. The Scientist Noticed That The Birds Only Appeared At Certain Times Of The
Day, Always Singing The Same Song During Those Times.
3. What Is The Main Purpose Of Conducting Experiments? (Outcome #Ib) (DOK
1) (Paired Item1)
A. Proving A Theory
B. Making Initial Observations
C. Disproving A Hypothesis*
4. The Attempt To Disprove A Hypothesis Is Accomplished By Which Of The
Following Tasks? (Outcome #Ib) (DOK 1) (Paired Item 2)
A. Conducting Experiments*
B. Making Initial Observations
C. Proposing A Theory
5. A Scientist Wishes To Test A New Antibiotic’s Ability To Treat Stubborn Bacterial
Infections. He Tests His Hypothesis That The Antibiotic Works Better Than Existing
Treatments By Giving Bacterial Infections To Mice And Treating Them With The
Antibiotic. He Then Determines How Many Of The Mice Recover From Their
Infections. What Is Missing From His Experimental Design? (Outcome #Ib) (DOK 3)
(Paired Item 1)
A. He Is Missing A Control Group Of Mice That Received A Half Dose Of The New
Antibiotic.
B. He Is Missing A Control Group Of Mice That Did Not Receive The New Antibiotic.*

C. Nothing Is Missing—He Has Done Everything He Needs To Do For This To Be
A Successful Experiment.
6. A Scientist Wants To Determine Whether A New Chemical She Isolated Can
Cure A Certain Disease. To Test Her Hypothesis That The New Chemical Cures
The Disease More Effectively Than Current Treatments, She Infects Mice With
The Disease And Gives Them The New Chemical. She Then Assesses How Many
Mice Were Cured Of The Disease. What Is Missingfrom Her Experimental
Design? (Outcome #Ib) (DOK 3) (Paired Item 2)
A. She Is Not Missing Anything—Her Experimental Design Is Adequate To
Test Her Hypothesis.
B. She Is Missing A Control Group Of Mice That Received A Half Dose Of The New
Chemical.
C. She Is Missing A Control Group Of Mice That Did Not Receive The New Chemical.*
7. A Scientist Believes That She Has Found A New Life Form. Which Of The Following
Conditions Is Not Considered Essential In Determining Whether The Putative New
Life Form Is Alive? (Outcome #Ic) (DOK 2) (Paired Item 1)
A. The Creature Possesses Purposeful Anatomical Structures That Differ
From One Another.
B. The Creature’s Body Is Bilaterally Symmetrical.*
C. The Creature Seems To React To Being Touched.
8. A Scientist Discovers A Putative New Life Form And Notes That The Creature’s Body Is
Bilaterally Symmetrical And Consequently Satisfies The Criteria For Defining Life In
Which Of The Following Categories? (Outcome #Ic) (DOK 2) (Paired Item 2)
A. None, Symmetry Is Not A Basic Characteristic Of Life*
B. Order
C. Growth And Development
9. Which Of The Following Lists Correctly Presents Levels Of Organization From Simplest To
Mostcomplex? (Outcome #Ic) (DOK 2) (Paired Item 1)
A. Organs, Organ Systems, Organelles, Organisms
B. Biosphere, Atoms, Communities, Organisms
C. Molecules, Cells, Populations, Ecosystems*
10. Which Of The Following Lists Correctly Presents Levels Of Organization From
Most Complex Tosimplest? (Outcome #Ic) (DOK 2) (Paired Item 2)
A. Cell, Organelle, Atom, Molecule
B. Biosphere, Community, Organism, Organ System*
C. Macromolecule, Population, Community, Ecosystem
11. An “Educated Guess” As To What Causes An Observed Phenomenon Is Known As
A: (Outcome #1) (DOK 1)
A. Theory
B. Hypothesis*
C. Control
12. Why Are Theories Stronger And More Reliable Than Hypotheses? (Outcome #1) (DOK 2)
A. Because We Believe In Them More
