Suppose that a living wooly mammoth had been discovered by Lewis and Clark. How would this discovery have affected the claims of those who thought that America had an inferior climate?A.It would have strengthened their claims, because mammoths are a more primitive species than modern elephants.B.It would have strengthened their claims, because a climate suited to mammoths would have been unsuitable for humans.C.It would have weakened their claims, because mammoths would have been larger and stronger than animals then living in Europe.D.It would have weakened their claims, because it would have demonstrated that the unsettled areas of America had inferior climates.Review ScreenuPreviouslNavigationNextm

What was one outcome of the Lewis and Clark expedition? A:A. good relations with western American IndiansB:B. war between the United States and SpainC:C. discovery of gold in the "Great American Desert"D:D. colonization east of the Mississippi River

According to the passage, early Americans believed in climate change because:A.they expected the settlement of America would lead to a more hospitable climate.B.their records showed a gradual warming pattern in the United States.C.their animals and plants were less evolved than those in Europe.D.they had seen it happen in Europe after the land was cultivated.

What era would this live in? (Woolly Mammoth)

Mammoths were giant terrestrial mammals that roamed the earth approximately 126,000 to 5,000 years ago during the Late Pleistocene epoch. Emma Reynolds, Marco Rossi, and H. Thomas Kell Jr. analyzed carbon-13 isotopes in mammoth tooth enamel to estimate probable mammoth body temperatures and concluded that mammoths were homeothermic—that is, they utilized internal metabolic processes to sustain a stable body temperature in various environmental temperatures. Reynolds, Rossi, and Kell assert that homeothermy would have permitted mammoths to extend their range into relatively chilly polar regions.12 Mark For Review12Which finding, if true, would most directly support Reynolds, Rossi, and Kell's claim?A) Mammoths' likely body temperatures are easier to determine from tooth enamel carbon-13 isotope data than the body temperatures of non-homeothermic Late Pleistocene terrestrial mammals are.B) Fossils of both mammoths and non-homeothermic terrestrial mammals have been found in roughly equal numbers in regions known to be near the poles during the Late Pleistocene, though in lower concentrations than elsewhere.C) Several mammoth fossils have been found in regions known to be near the poles during the Late Pleistocene, while relatively few fossils of non-homeothermic terrestrial mammals have been found in those locations.D) During the Late Pleistocene, land temperatures were likely higher throughout the mammoths' range, including near the poles, than land temperatures at those same latitudes are today.
