Across
- 2. suppress unwanted microbes and encourage desired microbes
- 3. useful for identifying eukaryotes, but tells little about phylogenetic relationships
- 6. the sharing of electrons between 2 or more atoma to form a molecule or compounds
- 10. requires oxygen
- 17. enriched with 3-5% sheep blood
- 18. formed by an attraction between 2 different atojms that are more significantly different in electronegativity than thoses atoms in polar covalent bonds
- 20. used by a few bacterial species
- 22. consists of 2 monosaccharides joined by a covalent bond called a glycosidic bond
- 25. solution passed through a filter that collects bacteria
- 26. tolerate but cannot use oxygen
- 27. a rare autosomal recessively-inherited trait
- 32. only contains one species or strain
- 33. the smallest unit of matter that still retains the properties of an element
- 34. microbes growing in or on a culture
- 38. able to grow with or without oxygen
- 42. allow distinguishing of colonies of different microbes on the same plate (BAP blood agar)
- 43. introduction of microbes into a medium
- 44. who reported that living things are composed of little boxes, or "cells"
- 45. partial lysis of red blood cells, green zone
- 49. the hypothesis that living cells aires only from preexisting living cells
- 50. bacteria agglutinate (clump) when mixed with antibodies produced in response to the bacteria
- 51. the simple sugars (monomers)
Down
- 1. total lysis of red blood cell, clear zone
- 4. found between electrons of different elements because they are not always shared equally
- 5. determine presence of bacterial enzymes
- 7. cell division process used by most bacteria
- 8. the hypothesis that life arises from nonliving matter
- 9. extracts and digests of yeasts, meat, or plants; chemical composition varies batch to batch
- 11. require oxygen concentration lower than air
- 12. population of cells derived from a single parent cell
- 13. the three domain system was developed by who
- 14. a population of cells with a high degree of genomic similarity
- 15. adds water to break down polymers into their component monomers
- 16. who demonstrated that microorganisms are present in the air
- 19. genetically different cells within clone, arising usually due to mutations
- 21. the science of classifying organisms
- 23. hydrolysis is an example of what
- 24. can differentiate between species and strains within species
- 28. found between electrons of the same element becuse they are shared equally
- 29. growth of obligate anaerobes
- 30. nutrients prepared for microbial growth
- 31. bacteria grown in laboratory media
- 35. no lysis of red blood cell, no change to media
- 36. involved in 70% of infections (catheters, heart valves, contact lenses, dental caries)
- 37. no living microbes
- 39. first living microbes were observed, documented with detailed drawing by who
- 40. gram staining, acid-fast staining
- 41. are found between molecules, not within them
- 46. unable to use oxygen and most are harmed by it
- 47. measurement of cloudiness with a spectrophotometer
- 48. amount of metabolic product is proportional to the number of bacteria
