Viruses consist of DNA or RNA but not both.<br>b. Viruses are acellular but are surrounded by a protein coat.<br>c. Viruses can infect bacteria, plants, and animals.<br>d. Viruses do not need host cells to survive and grow.<br>ANS: D<br>Viruses need to have a host cell because they do not have the ability to reproduce or nourish<br>themselves without the host\u2019s cellular mechanisms.<br>OBJ: Level 2: Interpretation<\/li>\n\n\n\n<li>Diagnostic microbiologists apply placement and naming of bacterial organisms into all the<br>following categories, except<br>a. order.<br>b. family.<br>c. genus.<br>d. species.<br>ANS: A<br>Clinical microbiologists use the family, genus, and species taxonomic categories to identify<br>species that are important for diagnostic diseases.<br>OBJ: Level 1: Recall<\/li>\n\n\n\n<li>Bacterial species that exhibit phenotypic differences are considered<br>a. biovarieties.<br>b. serovarieties.<br>c. phagevarieties.<br>d. subspecies.<\/li>\n<\/ol>\n\n\n\n<p>ANS: D<br>Biovarieties vary based on biochemical test results, serovarieties vary based on serologic test<br>results, and phagevarieties is a fictitious word.<br>OBJ: Level 2: Interpretation<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"13\">\n<li>What structure is described as a phospholipid bilayer embedded with proteins and sterols that<br>regulates the type and amount of chemicals that pass in and out of a cell?<br>a.

The cholesterol molecules in the plasma membrane are found solely in the interior<br>of the membrane.<br>ANS: A<br>The plasma membrane is designed so that the hydrophilic heads of the phospholipid<br>molecules are positioned to make contact with the intracellular and extracellular fluids. The<br>hydrophobic tails of the phospholipid molecules face away from the fluids and form the<br>interior of the plasma membrane. The tails of the phospholipid molecules are hydrophobic,<br>not hydrophilic. The ion channels extend through the cellular membrane.
