Lobed Nucleus
4. Macrophages D. Include NK Cells, B Cells, And T Cells; Function In Innate And
Adaptive Immunity
,5. Dendritic Cells E. Phagocytic Cells That Patrol Bloodstream Or Reside
Permanently In Tissues
6. Eosinophils F. Found In Low Blood Concentration; Fight Parasitic Infections;
Involved In Allergies
Correct Matches:
1–C
2–D
3–A
4–E
5–B
6–F
Question 3 (True Or False)
Barrier Defenses Fall Under The Adaptive Arm Of The Immune System.
A) True
B) False
Question 4 (Multiple Choice – Select All That Apply)
Which Of The Following Statements Is/Are True Of Eukaryotic Cells?
A) DNA Is Housed In A Membrane-Bound Nucleus
B) They Are Always Single-Celled
C) Bacteria Are Examples
D) All Of The Above Statements Are True
, Question 5 (Short Answer)
List The THREE Common Bacterial Shapes.
ANS. Cocci, Bacilli, Spiral
Question 6 (Explain/Describe)
Explain How Pathogens Use Capsules To Evade Host Cell Detection.
ANS.
Pathogens Can Form Protective Capsules That Mask Surface Antigens, Making
Them Difficult For The Immune System To Recognize. The Capsule Also Protects
Microorganisms From Degradation By Host Antimicrobial Proteins.
Question 7 (Short Answer – Explain/Describe)
Where Is Lysozyme Found? Describe How Lysozyme Destroys Pathogens That Have
Entered The Body.
ANS.
Lysozyme Is Found In Mucus, Tears, And Saliva. It Destroys Pathogens By
Interfering With The Peptidoglycan Cell Walls Of Bacteria, Leading To Bacterial
Destruction.
