Answers
Answer:
(D) he use flamingo necked flask.
Answer:
Louis Pasteur was successful in proving spontaneous generation wrong because the yeast ( and other microbes) used by him in one of the flask used was dead.
Explanation:
Spontaneous generation is the belief that life can be generated by non living things. Louis Pasteur was able to prove that spontaneous generation was impossible by using two flasks of boiled sterilized beef.
He exposed one the beef to air and the other was protected from the air. The beef that was left exposed to air clouded and the one that was sealed did not.
The beef that was exposed to air was contaminated by microbials and thus clouded because of microbial growth. The sealed one did not cloud proving that spontaneous generation is not possible.
