| which of the following statements is true | microbes are ubiquitous (virtually everywhere) |
| which of the following are even smaller than viruses | prions and viroids |
| Louis Pasteur | pasteurization introduced the terms aerobes and anaerobes developed vaccines for anthrax and rabies disproved spontaneous generation germ theory contributions that specific genes cause specific infections. ex: anthras, TB |
| Anton van Leeuwenhoek | first person to observe live bacteria and protozoa untrained father of microbiolgy created the single-lens/single microscope |
| Robert Koch | developed an experimental procedure that could be used to prove that a specific microorganism is the cause of a specific infectious disease methods of fixing, staining and photographing bacteria germ theory-led to Koch's Postulates cultivating bacteria on a olid medis |
| Rudolf Virchow | proposed the theory of biogenesis |
| Alexandre Emil Jean Yersin | discovered the causative agent of the plague |
| all infectectious diseases are caused by pathogens | all infectectious diseases are caused by pathogens |
| pathogens greathly out number nonpathogens | false (the reverse is true) |
| using microorganisms to clean up the environment is known as bioremediation | true |
| microorganisms are essential in the field of genetic engineering | true |
| microorganisms appeared on earth about 3.5 million years ago | false-3.5 billion years ago |

| Louis Pasteur and Robert Koch made significnt contributions to the "Germ Theory of Disease" | true |
| Pasteurization is a process that kills all microorganisms present in the liquid being pasturized | false-designed to kill pathogens |
| microorgaisms contribute more oxygen to our atmosphere than plants do | true |
| infectious diseases that are transmitted from animals to humans are known as zoonoses | true |
| anton van leeuwenhoek "1632-1723" | the "father of microbiology", but he was not a trained scientist. created the single len microscope. came up with the idea spontaneous generation or "abiogenesis". |
| rudolf virchow "1858" | first proposed the theory of biogenesis, which is that life can only arise from preexisting life. |
| louis pasteur "1822-1894" | came up with pasteurization, while trying to find a way to stop wine from spoiling. stated that specific microbes cause specific infectious disease. he developed vaccines, most known for rabies vaccine |
| robert koch "1843-1910" | developed methods of fixing, staining, and photographing bacteria. cultivated bacteria of solid media. one of his colleages was RJ petri-"petri dish". discovered the bacterium that causes tuberculosis. developed the skin test for TB. Koch's postulets. |
| a symbiont could be a (an) | commensal, opportunist, parasite |
| the greatest number and vaiety of indigenous microflora of the human body live in or on the | colon |
| escherichia coli living in the human colon can be considered to be a (an) | endosymbiont, opportunist, symbiont in a mutulistic relationship |
| which of the following sites of the hyman body does not have indigenous microflora | blood, lymp, spinal fluid, most internal tissues and organ, fetus, inner ear, eyes |
| which of the following would be present in hightes numbers in the indigenous microflora of the human mound | alph-hemolytic stereptocci |
| which of the follwoing would be present in highest numbers in the indigenous microflora of the skin | coagulase-neagtive staphylococci |

| microorganisms are used in which of the following industries | anitibiotic, chemical, food, beer, and wine |
| the term that best describes a symbiotic relationship in which two differnent microorgaisms occuppy the same ecologic niche, but have absolutely no efffect on each other | neutralism |
| neutralism | when two microorganisms occupying the same environmental niches have absolutely no effect on each other |
| synergism | bacterial vaginosis is an example of |
| commensalism | a symbiotic relationship of benefit to one of the symvionts, but neither beneficial nor harmful to the other ex: Demodex |
| parasitism | a symbiotic relationship of benefit to one of the symbionts and detrimental to the other ex: Trypansoma gamviense |
