  30. Where are most of the microorganisms found in the environment?
    Marine surfaces
  31. What was the leading cause of death in 1900's?
    Pneumonia and Flu
  32. What is the leading cause of death today?
    Heart disease and cancer
  33. Who is responsible for the discovery of microorganisms?
    Robert Hooke
  34. Who is responsible for the discovery of bacteria and the invention of the hand held microscope?
    Anton van Leeuwenhoek
  35. Who is responsible for the discovery of endospores?
    Ferdinand Cohn
  36. Structures in bacteria that are important in their survival.
  37. Who is responsible fore the mechanism of fermentation, the defeat of spontaneous generation, and the disproving of spontaneous generation?
    Louis Pasteur
  38. Who conducted the experiment to disprove spontaneous generation that involved an experiment in which he compared the growth of microorganisms in one flask containing sterile broth that was exposed to the air and one containing sterile broth that was not exposed to the air? The conclusion was microorganisms grew only in the flask exposed to the air, thereby refuting the idea that cells can arise spontaneously from nonliving matter.
