Question
Chapter 2, Problem 2Q
Summary Introduction
To explain:
The reason for the fact that the archaea and bacteria considered to be very closely related before the availability of molecular techniques on the basis of microscopy.
Concept introduction:
In earlier times, it was assumed that there were only two domains (Bacteria) and (Eukarya) based on differences of nuclei, cellular organelles, and the cytoskeleton. The “bacteria” living in very harsh conditions were identified and named archaea.

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. At 100X you are unable to see the diatom. Explain why. Explain what correction (s) should be made to allow you to see the diatom using the 100X lens. 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.arrow_forward
