in developing the cell theory, virchow proposed the idea that cells come from pre - existing cells. this was contradictory to the beliefs of most scientists at the time. louis pasteur provided proof of this when he performed an experiment with sterilized nutrient broth. the broth in straight neck flasks grew bacteria, but the flasks with curved necks did not grow bacteria.\nhow are scientific theories formed?\na from the opinions of very educated people\nb from one experiment of a famous scientist\nc from evidence gained by many experiments of many scientists\nd ignoring any experimental evidence that does not fit the theory

Answer

Brief Explanations:

Scientific theories are well - substantiated explanations of some aspect of the natural world. They are formed based on a large amount of evidence gathered from multiple experiments conducted by numerous scientists over time. One experiment or the opinion of a single educated person is not sufficient. Also, theories should account for all relevant evidence, not ignore contrary evidence.

Answer:

C. from evidence gained by many experiments of many scientists
