Mocrobiology Test 1

QuestionAnswer
1. Know the hierarchy of life in order of the individual to the biosphere and what each level consists of.
What two domains contain the prokaryotes?
Know some general characteristics of each of the groups of microorganisms,example,if a patient were diagnosed with a diseased caused by a single-celled microorganism with a nucleus and moved by means of a flagella,
4. With respect to nitrogen-fixation what is a legume, the root nodule, Rhizobium, leg-hemoglobin, and the nitrogen fixers in aquatic environments? Of course, what is nitrogen fixation?
5. What are trophic levels and the characteristics of each level?So, for example, how would you answer this question?A cow’s herbivorous diet indicates that it is a(n): primary consumer
What are the major groups of microbes that are decomposers?
What organisms would you find in the domain Eukarya?
7. What is Biosphere II and what was one of the reasons that it failed? You probably know that it had something to do with microbes
8. What did you learn about coral reefs and the importance of microbes in keeping them healthy? In the hierarchy of life where would you place a coral reef? Why are coral reefs so important? Why are some of the coral reefs dying?
9. Why are soil crusts important to most deserts of the world?
10. Who devised binomial nomenclature?
11. The world’s largest organism?
12. Yeast are considered to be in which major group of organisms?
13. What are mycorrhizae? What organisms are they in relationship with and what do they contribute to the relationship?
14. According to binomial nomenclature, what is the first term and what is the second? How do you write a scientific name?
15. What did Carl Woese use (in the cell) to come up with the three domain system?
16. What is nitrification and while we’re at it, denitrification?
17. If there were a lot of pollution in an air, what would happen to the lichens?
18. What does the term “symbiosis” mean?
19. Know the taxonomic levels or groups in order.
20. If a scientist were studying acellular microorganisms what area of microbiology would he/she be studying?
21. Why do microbes make such wonderful research “animals”?
22. How are viruses classified?
23. Do microbes constitute the largest component of the earth’s biomass?
24. What are the distinguishing features of the bacteria?
25. What did Leewenhoek do that is important with regard to microbiology?
26. What is a distinguishing characteristic of the Archaea?
27. What does a mycologist study? And what do phycologists study?
28. What book(s) have the most complete classification of bacteria and serve as the major reference for microbiologists?
29. Viruses are prokaryotes?
30. Nitrogen is necessary to make the organic molecules of life. Give 2 examples of organic compounds found in ourselves and microbes that contain nitrogen
Explain why we cannot utilize the nitrogen in the air to make our nitrogen containing compounds.
What organisms can utilize nitrogen? What is the name of the process and explain how they do it?
31. What are biogeochemical cycles?
hyphae
lichen
phylogeny and biomes
33. Be able to write an essay explaining why microbes are important to life on earth. Use four points to illustrate their importance.
34. What is the microbial connection between microbes and a cow? Legumes?

50. How would you classify coral?
51. In taxonomy, is the division the same as the family level?
52. What does ubiquity mean?
53. Really know the nitrogen cycle, especially about the nitrogen fixers. But you should know what ammonification, denitrification and nitrification are.
