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?...

Criteria for natural selection - Answer variation, heritable, influences fitness natural selection acts on __________ and evolutionary change acts on _____________ - Answer individuals, populations Artificial selection - Answer driven by humans selectively breeding How fast/far can artificial selection go? - Answer FAST -depends on how many genes -how much the phenotype is controlled by the environment FAR -presence of deleterious trade offs -limits of the genetic variation availab...

change from gen to gen via selection of heritable traits evidence for evolution - Answer - fossils - extinction - transitional forms - vestigial traits why is the myth about evolution being goal oriented false? - Answer species do not adapt because they "want" or "need" traits; they adapt them because an ancestor with that triat just so happened to reproduce sooner or more successfully than others why is the myth that evolution is a hierachy false? - Answer evolution is more a ne...
