ANS: D
The Chapter Begins By Discussing The Way Microbial Inhabitants Have Had To Evolve To
Survive In Many Different Niches And Habitats. It Discusses Slow Growers, Rapid Growers,

c. Carl Landsteiner
d. Michael Douglas
ANS: A
The Book Discusses Anton Van Leeuwenhoek As The Inventor Of The Microscope And The First

4. This Form Of DNA Is Commonly Found In Eukaryotic Cells.
a. Linear
b. Circular
c. Plasmid
d. Colloid
.
.
, ANS: A
Circular And Plasmid DNA Are Usually Found Only In Bacteria, Not Eukaryotic Cells. Colloid Is
A Property Of Protein Molecules And Is Not Associated With Nucleotides.
OBJECTIVE.: LEVEL 1: Recall
5. The Nuclear Membrane In Prokaryotes Is
a. Missing.
b. Impenetrable.
c. A Classic Membrane.
d. A Lipid Bilayer Membrane.
ANS: A
Prokaryotic Cells Do Not Have Any Membrane-Bound Structures In The Cytoplasm Including
A Structured Nucleus.
OBJECTIVE.: LEVEL 1: Recall
6. A Microorganism That Is A Unicellular Organism And Lacks A Nuclear Membrane And
True Nucleus Belongs To Which Classification?
a. Fungi
b. Bacteria
c. Algae
d. Parasite
ANS: B
Fungi, Algae, And Parasites Are Unicellular Eukaryotic Organisms That Contain A True
Nucleus. Bacteria Are Prokaryotic And Do Not Contain A True Nucleus Or Nuclear
Membrane.
OBJECTIVE.: LEVEL 1: Recall
7. In The Laboratory, The Clinical Microbiologist Is Responsible For All The Following, Except
a. Isolating Microorganisms.
b. Selecting Treatment For PATIENTS.
c. Identifying Microorganisms.
d. Analyzing Bacteria That Cause Disease.
ANS: B
Clinical Microbiologists Do Not Select The Treatment For PATIENTS. They Provide The Doctor
With The Name Of The Organism And The Antibiotics That Can Kill The Bacteria, But Not In
The Final Selection Of Treatment Protocols.
OBJECTIVE.: LEVEL 2: Recall
8. What Enables The Microbiologist To Select The Correct Media For Primary Culture And
Optimize The Chance Of Isolating A Pathogenic Organism?
a. Determining Staining Characteristics
b. Understanding The Cell Structure And Biochemical Pathways Of An Organism
c. Understanding The Growth Requirements Of Potential Pathogens At Specific Body Site
d. Knowing The Differences In Cell Walls Of Particular Bacteria
ANS: C
, By Understanding Growth Requirements, A Microbiologist Can Maximize The Chance Of
The Organism Being Isolated From A Culture. The Other Three Choices Are Used To
Identify A Bacterium Once It Has Grown On Media.

A Culture Has Both A Unicellular Form And A Filamentous Form. What Type Of Organism
Exhibits These Forms?
a. Virus
b. Fungi
c. Bacteria
d. Parasite
ANS: B
Viruses Typically Only Have One Form And Would Not Grow On Plate Media. Bacteria Have

OBJECTIVE.: LEVEL 2: Interpretation
11. Diagnostic Microbiologists Apply Placement And Naming Of Bacterial Organisms Into All
The Following Categories, Except
a. Order.
b. Family.
c. Genus.
d. Species.
ANS: A
Clinical Microbiologists Use The Family, Genus, And Species Taxonomic Categories To

OBJECTIVE.: LEVEL 1: Recall
12. Bacterial Species That Exhibit Phenotypic Differences Are Considered
a. Biovarieties.
b. Serovarieties.
c. Phagevarieties.
d. Subspecies.
.
.
, ANS: D
Biovarieties Vary Based On Biochemical Test Results, Serovarieties Vary Based On Serologic
Test Results, And Phagevarieties Is A Fictitious Word.

That Regulates The Type And Amount Of Chemicals That Pass In And Out Of A Cell?
a. Cell Wall
b. Mitochondria
c. Endoplasmic Reticulum
d. Plasma Membrane
ANS: D
The Cell Wall Is The Outer Covering Made Up Of Lipids. The Mitochondria Is A Cellular
Organelle That Is Considered The Powerhouse Of The Cell (Electron Transport And Oxidative
Phosphorylation Occur Here). The Endoplasmic Reticulum Is A Cellular Organelle Where Protein
Synthesis Occurs.
OBJECTIVE.: LEVEL 1: Recall
14. What Makes The Interior Of The Plasma Membrane Potentially Impermeable To Water-
Soluble Molecules?
a. The Hydrophobic Tails Of The Phospholipid Molecules Are Found There.
b. The Hydrophilic Tails Of The Phospholipid Molecules Are Found There.
c. The Ion Channels Are Found There.
d. The Cholesterol Molecules In The Plasma Membrane Are Found Solely In The
Interior Of The Membrane.
ANS: A
The Plasma Membrane Is Designed So That The Hydrophilic Heads Of The Phospholipid
Molecules Are Positioned To Make Contact With The Intracellular And Extracellular Fluids.
The Hydrophobic Tails Of The Phospholipid Molecules Face Away From The Fluids And Form
The Interior Of The Plasma Membrane. The Tails Of The Phospholipid Molecules Are
Hydrophobic, Not Hydrophilic. The Ion Channels Extend Through The Cellular Membrane.
The Cholesterol Molecules Also Extend Through The Plasma Membrane.
OBJECTIVE.: LEVEL 2: Interpretation
15. The Function Of A Cell Wall Is To
a. Regulate The Transport Of Macromolecules In And Out Of The Cell.
b. Provide Rigidity And Strength To The Exterior Of The Cell.
c. Provide Reserve Energy To The Eukaryotic Cell.
d. Protect The Eukaryote From Predators.
ANS: B
The Plasma Membrane Regulates The Transport Of Macromolecules In And Out Of The Cell,
Not The Cell Wall. The Mitochondria Provide Energy To The Eukaryotic Cell. Cell Walls Are
Not Able To Protect A Eukaryotic Cell From Predators.
