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
, B. Because They Have A Control Group
C. Because They Are Based On Many Experimentally tested hypotheses*
