In your opinion, what additional controls and measurements could Frances Redi have done to prove that rotting of raw meat is caused by live bacteria?

Which of the following situations describes a scenario in which allopatric speciation might occur?
A) A mutation changes the pollinator a plant can utilize. B) An earthquake separates a lizard population into two groups. C) A mutation makes certain frogs mate two days earlier in the season. D) A pair of birds colonizes an island with numerous empty niches. Refer to the scenario below, and then answer the following question(s). Species of fruit fly larvae in the genus Rhagoletis each feed on a particular kind of fruit. Rhagoletis pomonella feeds on the small red fruit of the hawthorn tree. In 1865, farmers in the Hudson River valley found that R. pomonella flies had begun attacking their apples and then spread to apple orchards in adjacent areas of Massachusetts and Connecticut. These now separate varieties of flies, the apple and haw flies, usually don't interbreed with each other because their periods of mating coincide with the different ripening times of apples and hawthorn fruit. Each variety is becoming specialized to feed and reproduce in its own particular microhabitat and may be transitioning to separate species.
