Why might Pasteur's experiment be inconclusive? - Answer The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? - Answer To ensure that results were not achieved by random chance What is the definition of a replicate? - Answer Unit that shares a common thing (4 mice in one cage = 1 replicate) What does the law of succession suggest?...
