Which statement about dispersal is false?(A) Dispersal is a common component of the life cycles ofplants and animals.(B) Colonization of devastated areas after floods or volcaniceruptions depends on dispersal.(C) Dispersal occurs only on an evolutionary time scale.(D) The ability to disperse can expand the geographic distribution of a species.
For the metapopulation of Daphnia in Scandinavian freshwater pools, which situation would be most likely to result in maintenance of the metapopulation, rather than its extinction? A) Immigrants increase the genetic diversity of pools, slightly increasing r. B) Years of drought decrease the average size of all pools. C) Small pools “wink off” and are not repopulated by dispersal from larger pools. D) The pools are mostly small, and there is no dispersal among them. E) Dispersal among pools is infrequent, and many pools reach zero density.

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
