22 For most of the first 1.800 years in the common era, most people, scholars, did not believe in sexual or asexual
reproduction for many organisms. They thought many creatures, including frogs and mice, came from nonliving things. This was the
theory of spontaneous generation. For example, maggots were believed to simply appear in meat as it spoiled. Today we know that
maggots come from eggs that were laid on or in the meat by their mothers,
Louis Pasteur proved that living organisers do not just appear Broth that is left sitting out for a while will grow cloudy as small
organisers live and grow in it. Louis Pasteur boiled broth and let it cool without coming into contact with any "particles" in the air
Broth treated that way did not grow cloudy
Louis Pasteurs experiment showed that small organisers that live in broth do not come from the broth itself. Which of the following
best describes this statement and how it changed what scientists know?
A. It is a scientific ornarvation that goes against the theory of spontaneous generation, so the theory must be wrong,
OB. It is a set of detailed observations of how single-celled organisms live and reproduce
C. It is a scientific theory of how life begins that fits the facts better than spontaneous generation,
D. It is a result that was predicted by the theory of sexual reproduction, proving that theory to be correct,
