Model Paper 10 — NEET STD 11 Science — Question

A.  Pasteur
Explanation:
Pasteur was the first to propose that diseases were caused by microscopic organisms. The final proof of germ theory came when Pasteur was able to grow the anthrax bacillus in culture. Although anthrax had been isolated by Robert Koch, opponents believed that the spores he found could have been containments in his culture medium. Pasteur placed a drop of blood from a sheep dying of anthrax into a sterile culture and allowed the bacilli to grow. He repeated this process until none of the original cultures remained in the final dish. The final culture produced anthrax when injected into sheep, showing that the bacillus was responsible for the disease.
