Question

1. What is the total magnification of a compound light microscope with an objective lens magnification of 40X and an ocular lens of 10X? 2. Why is immersion oil necessary at 1000X but not with the lower power objectives? 3. What are the advantages of brightfield, darkfield, and phase-contrast microscopy? 4. Why won't other bacteria fluoresce in the FTTA-ABS test? 5. What is the principal use of SAM? 6. How do TEM and SEM images of the same organism differ? 7. What is the principle employed in scanned-probe microscopy? 8. How can the Gram reaction be useful in prescribing antibiotic treatment? 9. Why is Mycobacterium tuberculosis easily identified by the acid-fast stain? 10. Of what value are capsules, endospores, and flagella to bacteria?
