Awindstorm transports a few seeds of a plant species from island a, where the species is abundant, to island b, where prior to this event the plant species was not found. the environmental conditions on the two islands are very similar, but the islands are located far away from one another. over time, a small population of this plant becomes established on island b. a biologist samples plants on both islands and finds that allele frequencies on island a differ substantially from allele frequencies on island b at several genetic loci not known to affect survival or reproduction. based on this information, the observed genetic changes mostly likely resulted from

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
