Explanation:
<span>This
is standard procedure. It's easier to focus and locate the specimen
under low power using the coarse adjustment; you get a larger field of
view. Also it's a safety procedure. The high power objective has a
relatively long length and there is a possibility of breaking the glass
coverslip and/or slide if the coarse adjustment is used. Most
microscopes are "bifocal", that is, in switching from low to high power,
the image is nearly in focus with minor adjustment with the fine
adjustment. </span>
Answer:
Explanation:
A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor. Phylogenies are useful for organizing knowledge of biological diversity, for structuring classifications, and for providing insight into events that occurred during evolution. Furthermore, because these trees show descent from a common ancestor, and because much of the strongest evidence for evolution comes in the form of common ancestry, one must understand phylogenies in order to fully appreciate the overwhelming evidence supporting the theory of evolution.
