    Spontaneous Generation
  16. Why is rain an example of Spontaneous Generation?

  27. What were the results of the Sealed Flask in the 1st Broth Experiment?
  28. Explanation as to why one flask was cloudy and the other one wasn't in the 1st Broth Experiment?
    The one that was left open, air made it cloudy. Air didn't touch the sealed one so it wasn't cloudy.
  29. Who perfomed the 2nd Broth Experiment?
  30. How did the 2nd Broth Experiment change from the 1st one?
    The flask were made into 2 different shapes. 
  31. How come one flask was cloudy and the other one was clear in the 2nd Broth Experiment?
    There's particles in the air that made it cloudy
