Number of individuals 10 8 6 4 64 2 0 6 On balloon vine fruits Beak- Museum-specimen average On introduced species 8 10 11 Beak length (mm) Soapberry bugs use needlelike "beaks" to feed on seeds within the fruits of various plants. Bugs feed most successfully when their beak length matches the size of the fruit on which they are feeding. For 25 years, populations of soapberry bugs in central Florida have been feeding on small goldenrain tree fruits that were introduced to the area rather than on the larger native balloon vine fruits that serve as food for other soapberry bug populations. Beak lengths of soapberry bugs are variable but the average beak length is shorter in soapberry bug populations that feed on goldenrain tree fruits than in populations that feed on balloon vine fruits, as shown in the graph. How does natural selection act on beak length in soapberry bug populations? Natural selection decreases beak length in soapberry bug populations. Natural selection increases beak…

WRITE ABOUT A THEME: INTERACTIONS In Batesianmimicry, a palatable species gains protection by mimickingan unpalatable one. Imagine that individuals of a palatable,brightly colored fly species are blown to three remote islands.The first island has no predators of that species; the second haspredators but no similarly colored, unpalatable species; and thethird has both predators and a similarly colored, unpalatablespecies. In a short essay (100–150 words), predict what mighthappen to the coloration of the palatable species on each islandthrough time if coloration is a genetically controlled trait.Explain your predictions
Mclver beetles come in three colors: black, white, and brown. They are consumed by the Foust finch. To avoid predators, the beetles hide on the bark of trees in their environments. If the number of trees with black bark was significantly greater than the number of trees with white or brown bark, what would be the effect on the predation of Mclver beetles by the Foust finches? Far fewer black beetles would I + Which of the five conditions of Hardy-Weinberg equilibrium would be violated in this situation? V [ Select ] Genes are now mutating. Mating is no longer random.
