12. The use of bacteria as model organisms is supported by all of the following except: a) they have been widely studied b) they use similar biological processes to all other forms of life c) they are cheap and easy to maintain in the lab d) they are very closely related to humans e) they are easily manipulated 13. Microbes which survive well in extremely salty environments are referred to as? a) Alkaliphiles b) Acidophiles c) Halophiles d) Xerophiles 14. is credited with discovering the concept that some microbes form heat resistant endospores. a) Ferdinand Cohn b) John Snow c) Robert Koch d) Louis Pasteur e) Oliver Holmes 15. In one of the labs, we used agar plates containing sheep's blood which turned the agar a dark red. Upon examination of the results, all of your classmate's plates displayed cream colored "lawns" with some scattered colonies. For all plates the agar was still red except for one colony with a patch of clear media around it. What do these results indicate? a) all have ? (alpha) - hemolysis b) all have ? (beta) - hemolysis c) all have ? (gamma) - hemolysis d) one student had ? - hemolysis, the rest ? - hemolysis e) one student had ? - hemolysis, the rest ? - hemolysis 16. Based on the results above (#15), which of the following assumptions made by the students would be correct? a) One student had strep throat b) All students had strep throat c) No students had strep throat d) No conclusions can be made 17. Disease causing microorganisms are called a) pathogens b) eukaryotes c) decomposers d) bacteria e) viruses 18. Microorganisms are best defined as organisms that a) lack a nucleus b) cause human disease c) only grow in laboratories d) are too small to be seen with the unaided eye 19. In the name Staphylococcus aureus, which name represents the genus when using the classification of microorganisms? a) Staphylococcus b) aureus c) epithet d) both a and b 20. Scientists would utilize in a microbiology lab while trying to determine which microorganism is the cause of a newly discovered disease. a) Koch's Postulates b) Antibiotics c) Nutrients d) Cell Theory 21. Which of the following microbes would have belonged to the Monera Kingdom before being reclassified as a Domain? a) fungi b) protozoa c) viruses d) algae e) bacteria 22. "Saprophytes" like __ are a critical component of nutrient cycling on the planet. a) Protists b) Algae c) Fungi d) Virus 23. Which of the following fields of microbiology deals with the use of microbes to clean up the environment? a) Immunology b) Bioremediation c) Medical Microbiology d) Agricultural Microbiology
