BIO 120 Exam Study QUESTIONS WITH DETAILED VERIFIED ANSWERS | A+ GRADE ASSURED Pasteur's experiment provided conclusive evidence to reject the spontaneous generation hypothesis, which states that cells arise from nonliving material. As a consequence, his results supported the all-cells-from-cells hypothesis. Which element of Pasteur's experimental design was most important and why? His two treatments differed only in the shape of the flask, resulting in exposure of only one of the treatm...
