What is Germ Theory?

• The idea that disease is caused by microorganisms invading the body.

• The belief that diseases are caused by foul-smelling air.

• The theory that life arises spontaneously from non-living matter.

• The concept that diseases are caused by an imbalance of bodily fluids.

Who were the two microbiologists involved in proving Germ Theory?

• Robert Koch and Edward Jenner

• Louis Pasteur and Robert Koch

• John Tyndall and Joseph Lister

• Edward Jenner and Louis Pasteur

What did Pasteur prove with his experiments on milk?

• Milk goes off due to bacteria in the air.

• Milk sours because of miasma.

• Milk spoils due to spontaneous generation.

• Milk curdles due to an imbalance of humors.

What was Robert Koch's contribution to Germ Theory?
