Why might Pasteur's experiment be inconclusive? - 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? - To ensure that results were not achieved by random chance What is the definition of a replicate? - Unit that shares a common thing (4 mice in one cage = 1 replicate) What does the law of succession suggest? - As one species disap...

Suppose you take a drug that blocks your ability to secrete certain compounds in urine.

Why did amphibians move to land? - Unexploited food and niches - aquatic niches occupied - Lack of large terrestrial predators - Low O2 in warm water - unlimited O2 on land What are the three main diversifications of reptile and amphibian phylogeny? When did they begin to diversify? Ichthyostega - Paleozoic Devonian Leptospondyli - Paleozoic Carboniferous Temnospondyli - Paleozoic Carboniferous What was the name of the radiation that created the groups of amphibians we see today? When wa...
