When populations of closely related pied flycatchers and collared flycatchers live in different geographic areas, the males of both species look a lot alike. however, when populations of the two species share a common geographic area, there are significant differences in the appearance of the two species. what conclusions might you draw from this situation? (ebook module 14.10)a. even though the colors of the males of the two species are very similar in the geographically isolated populations, you would expect that when researchers performed mate-choice experiments, females would never chose males from the wrong species. b. this is a case of random variation within the population. c. this is a case where hybrid offspring of the two species are less fit than either of the parent species. in the geographic areas where the populations overlap, natural selection has reinforced color differences that serve as reproductive barriers between the two species. d. hybrid offspring of the two species are more fit than either of the parent species. eventually the two hybridizing species will fuse into one.

Governor reagan: mr. ellis, i think this idea that has been spawned here in our country, that inflation somehow came upon us like a plague and therefore it's uncontrollable and no one can do anything about it, is entirely spurious, and it's dangerous to say this to the people. when mr. carter became president, inflation was 4.8 percent, as you said. it had been cut in two by president gerald ford. it is now running at 12.7 percent. president carter also has spoken of the new jobs created . . but that can't hide the fact that there are 8 million men and women out of work in america today, and 2 million of those lost their jobs in just the last few months. mr. carter had also promised that he would not use unemployment as a tool to fight against inflation. and yet, his 1980 economic message stated that we would reduce productivity and gross national product and increase unemployment in order to get a handle on inflation, because in january, at the beginning of the year, it was more than 18 percent. which reasons and evidence does reagan use to support his argument? check all that apply. (1) the gross national product in 1979 (2) the gross national product in 1980 (3) the decrease in inflation rates (4) the increase in inflation rates (5) the number of jobs lost (6) the number of jobs created
