  6. ___________ have membrane-bound nucleus. (true nucleus)
  7. Level of Control (Biosafety Levels)

    BSL 1
    not known to cause disease (ex. E coli, Anthrax)
  8. Level of Control (Biosafety Levels)

    BSL 2
    associated with human disease (ex. Measles, Salmonella; Bloodborne, and can come from human bodily fluids)
  9. Level of Control (Biosafety Levels)

    BSL 3
    indigenous/exotic agents associated with human disease and with potential for aerosol transmission (ex. Tuberculosis)
  10. Level of Control (Biosafety Levels)

    BSL 4
    life threatening nature (ex. ebola)
  11. what are some control levels?
    • 1. PPE
    • 2. engineering (ventilating systems, incubators, etc)
    • 3. administrative (immunization)
  12. Aseptic Technique
    prevents contamination from unwanted microorganism.
  13. claim that living cells can arise from pre-exsisting living cells
    Theory of Biogenosis
  14. _________ claims thats microorganisms might cause disease
    Germ Theory Disease
  15. Cell Theory of Life
    all living things are composed of cells.
  16. Diplococci

  24. coccobacillus
  25. vibrio
  26. spirillum
  27. spirochete
  28. __________ cell wall consist of many layer of peptidoglycan and also contains teichoic acids. (semi permeable; Thick walls)
  29. ___________ bacteria have lipopolysaccharide-lipoprotein-phospholipid outer membrane surrounding a thin peptidoglycan layer. (selective permeable; Thin walls)
  30. mycoplasma
    doe not have a cell wall, but has sterol (fatty acid)
  31. passive transportation
    materials move from area of higher to lower concentration and no energy is expended by the cell
  32. simple diffusion
    molecules and ions move until equilibrium is reached
  33. facilitated diffusion
    substances are transported by transporter protein across membranes from areas of high to low concentrations
  34. osmosis
    movement of water from areas of high to low concentration across a selectively permeable membrane until equilibrium is reached
