, Chapter 01
1. Two Of The Main, Early Theories Proposed To Explain How Antigen-Specific Antibodies Develop
Were The Instructional Theory And The Selective Theory. How Did The Two Differ? Which Was
Ultimately Shown To Be CORRECT?
CORRECT ANSWER: The Selective Theory Says That, When An Antigen Receptor Binds With An
Antigen, The Cell Becomes Activated (Or The Cell Is Selected To Proliferate And Secrete More Copies
Of The Receptor). The Instructional Theory Says That The Antigen Receptor Molds Itself To The
Antigen. The Selective Theory Was Shown To Be Correct.
2. Often, Serendipity Plays A Role In Significant Scientific Discoveries. In Your Own Words,
Explain How Serendipity Led Pasteur To Discover A Cholera Vaccine.
CORRECT ANSWER: Pasteur Developed The Vaccine In Chickens, Which Were In Short Supply. He
Challenged Groups Of Chickens With Cholera Bacteria—Some Of Which Were Previously Exposed To
An Attenuated Version Of Cholera Bacteria. Only The Previously Exposed Animals Were Protected
From A New Challenge, Which Led To The Use Of Weakened Pathogens As Vaccines.
3. Despite Its Having Been Eradicated On A Global Scale, Smallpox Is Presently Considered A
Potential Bioterrorism Threat. Why? Use Evidence To Support Your Answer.
CORRECT ANSWER: After Eradication Was Achieved, Smallpox Vaccination Programs Largely
Ended. As Populations Continued To Grow Over Time, An Ever-Increasing Percentage Of The Human
Population Remains Unvaccinated And Thus, Is Still Susceptible To The Disease.
4. Prior To 1999, It Was Claimed That A Thimerosal Additive In Vaccines Was Contributing To The
Rising Incidence Of Autism. If The Claims Were True, What Resultant Trend Might You Expect To
Observe In The Rate Of Autism Once Thimerosal Was Removed From Vaccines?
CORRECT ANSWER: One Would Reasonably Expect A Decrease In The Rate Of Autism. However,
Cases Of Autism Continued To Rise After Thimerosal Was Removed From Vaccines In 2001.
5. Given The Discovery And Development Of Effective Antibiotics, Make An Argument For The
Continued Use Of Vaccines Against Bacterial Pathogens. Use Evidence To Support Your Answer.
CORRECT ANSWER: Antibiotics Are Used For Treatment Of Disease, Not Typically For Prevention.
Antibiotic Treatment Is Not Foolproof (Considering The Rising Incidence Of Antibiotic Resistance).
Vaccines Are A Preventative Measure, And Prevention Is The Gold Standard For Infectious Disease
Control Measures.
,6. You Have A Friend Unfamiliar With Immunology, And He Asks You The Following Question: "Why
Do I Need The Flu Shot Every Year, But Don't Need An Annual Chickenpox Vaccine?" As A Student Of
Immunology, How Would You Explain This Discrepancy To Your Friend? Use Evidence To Support
Your Answer.
CORRECT ANSWER: The Virus That Causes The Flu Changes Every Year - As A Result, A New Flu
Vaccine Must Be Prepared Each Year Based On A Predication Of The Most Common Forms Of The
Virus Likely To Be Encountered. Vaccines Are Specific In The Type Of Pathogen Against Which They
Protect, And Protection Against One Type Does Not Guarantee Protection Against Pathogens That Are
Closely-Related.
7. Provide One Benefit And One Drawback Of Generating Random Recognition Receptors
During The Development Of B Cells.
CORRECT ANSWER: A Benefit Is Having The Capacity To Recognize And Respond To Diverse
Pathogens As They Evolve. A Drawback Is That Some Recognition Receptors Could Potentially
Recognize And Target Host Antigens.
8. A Portion Of Our Immune Systems' White Blood Cells Is Constantly Circulating Throughout The
Body Via Circulation And Lymphatics. What Is The Benefit Of Such Circulation?
CORRECT ANSWER: The Circulation Of The White Blood Cells Allows For A More Comprehensive
Surveillance Of The Body For The Presence Of Potential Pathogens. A Significant Portion Of The
Human Body Is Constantly Exposed To Potential Microbial Pathogens.
9. Complete The Following Table By Comparing And Contrasting Innate And Adaptive Immune Responses.
Innate Immunity Adaptive Immunity
Is Mediated By What Cells?
What Do They Recognize?
How Are The Receptors Encoded?
Why Can't They Control All Infections Alone?
What Do They Do In Response To Antigen?

10. What Are The Hallmarks Of Inflammation? Describe The Physical Characteristics Of
Someone Experiencing An Inflammatory Response.
CORRECT ANSWER: Redness, Swelling, Heat, Pain. Someone Experiencing Inflammation Might Have
Localized Swelling And Redness Or Itching Or May Be Experiencing Faintness Due To A Lowering Of
Blood Pressure If More Severe.
11. Upon Receiving Immune Serum As A Treatment For A Venomous Snake Bite, Would The
Recipient Be Immune From Future Bites Of The Same Species?
CORRECT ANSWER: In The Short-Term, Probably, As The Serum Contains Protective Antibodies
Against The Venom. In The Long-Term, No, As Serum Treatment Is A Form Of Passive Immunity.
Passive Immunity Does Not Generate Long-Lived Memory Cells.
12. Provide One Common Feature Of And Two Differences Between B-Cell Receptors And Prrs.
CORRECT ANSWER: A Common Feature Is That They Both Are Used To Recognize Foreign
Antigens. A B- Cell Receptor Is More Selective Than A PRR. The DNA That Encodes For A PRR In An
Individual Is Inherited. The DNA That Encodes For A Mature B-Cell Receptor From An Individual Is
Not Passed On To Offspring.
