Who first opposed the spontaneous generation theory?

• Lazzaro Spallanzani

• Louis Pastuer

He formulated a set of postulates or standards to identify organisms that cause infectious diseases - 1843-1910

• Edward Jenner

• Robert Koch

• William Farr

• James Lind

Which scientist designed a special flask that allowed air in but kept microbes out and once and for all disproved spontaneous generation?

• Redi

• Needham

• Spallanzani

• Pasteur

In an anthrax experiment, the scientist Robert Koch began growing anthrax rods in sterile fluid. He then inserted the rods into mice. The infected mice always died. After dissection, Koch found that each mouse was infested with anthrax rods. What did Koch prove at the conclusion of this experiment?

• Some organisms are resistant to viral microbes

• Viruses cannot be spread through the air

• Viruses cause host cells to produce new proteins

• Specific microbes cause a specific disease

He is the "Father of Microbiology"

• Robert Hooke

• Anton Van Leeuweenhoek

His most famous achievement was that he used a single lens microscope to examine what seemed to be “everything.”

• Robert Hooke

• Anton Van Leeuweenhoek

Which scientist disproved spontaneous generation of large organisms by showing maggots came from flies not from rotting meat?

• Redi
• Needham
• Spallanzani
• Pasteur

What mistake did Needham make in his experiment?

• He failed to properly seal the flasks

• He failed to heat the broth

• He used too much broth

• He sealed the flasks completely

Who invented the first vaccine?

• Edward Jenner

• Louis Pasteur

• Alexander Fleming

• Robert Köch
