riefly describe the functions of the following parts of the microscope: course objective knob, condenser lens, diaphragm, objective lens, illuminator, fine adjustment knob, oil immersion.

Assume you are observing the diatom pictured in Figure 1 using the 10X lens in a compound light microscope. You move to the 40X lens and then again to the 100X lens by only rotating the turret (remember that the lenses are parfocal), without making any other adjustments to the microscope.          c) After making your adjustments, you notice that the midline of the diatom is in focus while the remainder is blurry. Explain, based on microscopy principles, why this has occurred Provide a description of the procedure to prepare an acidic stain of bacteria using Nigrosin as it would appear in the Methods section.

e) What is the total magnification of a specimen when viewed with the following objective: 400 Scanning High Power 400 Low power Oil Immersion

Of the four major types of microscopes, give an example of a scenario in which each would be the ideal choice for visualizing a sample. Stereo (Dissecting) Compound Confocal Electron

note: the circled option might be right or wrong

True-False The total magnification capability of a light microscope is only limited by the magnifying power of the lens system.

What is the purpose of using microscopes? If you need to move the microscope, describe how you should carry it. What three things change as you increase magnification? On the compound microscope, what power must be in place when you first find an image in themicroscope? On the compound microscope, which adjustment knob is used for bringing the specimen intofocus? On the compound microscope, which adjustment knob is used for sharpening the image of thespecimen after it is focused? On the compound microscope, which adjustment knob should you use on the high power? On the compound microscope, how do you change the objective lenses? What should be included when sketching or drawing what is seen through the microscope How do you properly use a microscope?
