The mistaken idea that living things can arise from nonliving things.
Correct Answer
Abiogenesis, spontaneous generationExplanation
Abiogenesis, also known as spontaneous generation, refers to the mistaken belief that living organisms can arise from nonliving matter. This idea was prevalent in ancient times, where people believed that things like maggots could spontaneously generate from decaying meat. However, this concept has been disproven by scientific experiments and observations, which have provided evidence for the theory of biogenesis, stating that living organisms only come from preexisting living organisms.Rate this question:

What was the name of the French chemist that helped to disprove spontaneous generation in the 1800's?
Correct Answer
Louis PasteurExplanation
Louis Pasteur was a French chemist who played a crucial role in disproving the theory of spontaneous generation in the 1800s. He conducted experiments that demonstrated that microorganisms do not arise spontaneously, but rather come from pre-existing microorganisms. His experiments with swan-necked flasks, where he boiled broth and observed no growth of microorganisms, provided evidence against the idea that life could spontaneously generate. Pasteur's work laid the foundation for the field of microbiology and helped to establish the germ theory of disease.Rate this question:
