Chapter 3, Problem 1CT
Summary Introduction
To determine: Whether compound light microscope or an electron microscope is the best choice to observe the surface of a microscopic section of bone.
Introduction: Microscope is an instrument used to observe minute organisms which are invisible to the naked eyes. The first microscope was devised by Anton von Leeuwenhoek and later several modifications were made to enhance its resolution and magnification. In the present day, state-of-the-art microscopes are available. The most commonly used microscopes are light microscope and electron microscope.

- 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.arrow_forward(a) If you were to magnify a cell 10,000-fold (typical of the magnification achievedusing an electron microscope), how big would it appear? Assume you are viewing a“typical” eukaryotic cell with a cellular diameter of 50 μm.(b) If this cell were a muscle cell (myocyte), how many molecules of actin could ithold? Assume the cell is spherical and no other cellular components are present; actinmolecules are spherical, with a diameter of 3.6 nm.
