Which scientist first disproved spontaneous generation byshowing that maggots only appear on decaying meat that hasbeen exposed to flies?(a) Lister(b) Pasteur(c) Hooke(d) Redi(e) Koch
What is the significance of Pasteur’s experiment to test the germ hypothesis?
a. It proved that heat can sterilize a broth.
b. It demonstrated that cells can arise spontaneously.
c. It demonstrated that some cells are germs.
d. It demonstrated that cells can only arise from other cells.
In 1864, Lister observed that patients recovered completely from simple fractures but that compound fractures had “disastrous consequences.” He knew that the application of phenol (carbolic acid) to fields in the town of Carlisle prevented cattle disease. Lister treated compound fractures with phenol, and his patients recovered without complications. How was Lister influenced by Pasteur’s work? Why was Koch’s work still needed?

As you know when you leave milk out it spoils. When Pasteur was alive, people thought that certain cows were more likely (than others) to cause milk spoilage because they produced an inferior type of milk. However Pasteur thought it might have to do with bacteria. He set up an experiment where he used two glasses of milk. In one of the glasses he added boiled milk. He discovered that the boiled milk did not spoil as fast as the un-boiled milk. He told his colleagues; and when his colleagues tried the experiment, they got the same results. What was the problem for Pasteur? What do you think was his hypothesis? What was the manipulated (independent) variable? What was the dependent variable he measured? Which group was the control: the boiled milk, or the unboiled milk.
