For each situation, indicate the type of speciation described.

hundreds of years ago true fruit flies in the america west coast only laid eggs on native hawthorns (a native apple tree), but today one group of true fruit flies lay eggs on hawthorns, and one group lay eggs on imported apples.

continents drift apart and separate previously connected lineages.

different environments on two sides of a barrier cause populations to diverge.

there are nine species of cichlid fish living in lake bermin (an isolated crater lake in cameroon). genetic data show that they are each others closest relatives, implying that they speciated there. the lake is only 0.6 km2 in surface area and 14.5 m deep, with no river feeders into or out of the lake.

a mountain range separates formerly connected populations of rabbits.

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
