I'm a freshman in college - need help answering another one of these "challenge questions"
The classic experiment by Pasteur tested the hypothesis that cells arise from other cells. In this experiment cell growth was measured following sterilization of broth in a swan-neck flask or in a flash with a broken neck:
a. Which variables were kept the same in these two experiments?
b. How does the shape of the flask affect the experiment?
c. Predict the outcome of each experiment based on the two hypotheses.
D. Some bacteria (germs) are capable of producing heat-resistant spores that protect the cell and allow it to continue to grow after the environment cools. How would the outcome of this experiment have been affected if spore-forming bacteria were present in the broth?
Appreciate the help - thanks!
