During the rainy season, and just as the dry season starts, food is abundant for all finches. however, as the dry season wears on, the seeds they eat become harder to find and competition becomes an important factor in survival. when a serious drought lasting 2.5 years hit daphne, the only finches that survived were the ones that could find enough food; seeds that they could not split open did not contribute to survival. heavy mortality in a population means there is strong selection for heritable traits that individuals survive and reproduce. for example, g. magnirostris eat large seeds, and g. magnirostris can outcompete all other finches. the big birds and g. fortis fight over smaller seeds and water holes, but the big birds are dominant to g. fortis because they are almost twice the size of g. fortis. given what you know about g. fortis, g. magnirostris, and the big bird lineage, what do you predict will happen as the drought continues?

He did not infringe upon the policy making powers that he felt the constitution gave congress. but the determination of foreign policy became preponderantly a presidential concern. when the french revolution led to a major war between france and england, washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-british. rather, he insisted upon a neutral course until the united states could grow stronger. which provides the best objective summary of this excerpt? president washington made a good choice when he decided not to accept the recommendations of his advisors and instead insisted that the united states stay neutral during the war between france and england as president, washington believed that the united states should remain neutral in foreign policy even though he had advisors who recommended that he take sides during the war between france and england. washington did not make policy decisions during his presidency because he did not want to interfere with the policy-making powers that the constitution gave congress. washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-britis
