11.65 mllion years ago, an asterold collided with the earth off the coast of modem day Yucatan Peninsula, Mexico. In combination with other factors, like increased volcanic activity, this asterold Impacted llving things in Irreverslble ways. Select allcorrect statements regarding how these events could affect populations of organisms.Mammals underwent adaptive radiation, filling niches that dinosaurs and other species left vacant as mass extinctions occurred.The asteroid vaporized the dinosaurs, leaving fish and birds to diversify which decreased plant diversity.Global temperatures cooled rapidly, decreasing plant production, which decreased herbivorous dinosaur populations.Herbivorous dinosaur populations decreased, which reduced food for predatory dinosaurs.Global temperatures increased due to the impact and increased volcanic activity; this increased plant production, which increased herbivore dinosaur size.NEXTPREVIOUS 11 of 25Sign outINTL O 10:1824 1. Cheatgrass (Bromus tectorum) is a species of fire-adapted grass that was Introduced by humans to the western United States in the 1880's. Fire-adapted specles not only survive frequent fires, some require fire to release nutrlents or allow seeds togerminate.The Great Basin Desert is characterized by sagebrush and cold temperatures. The Mojave Desert is characterized by creosote bush, cacti, and yucca plants and very hot temperatures. Both deserts get very infrequent ralnfall. Deserts are not fire-adapted ecosystems.Since Cheatgrass was introduced, It has invaded both the Great Basin and Mojave Deserts, where fires now occur as often as every 3 to 6 years.Select any statement that is likely to be true regarding the effects of the inrtoduction of cheatgrass.Fires destroy cheatgrass and halt its invasion.Desert plants will rapidly adapt to frequent fires.Cheatgrass seeds survive and spread with each fire cycle. The frequent fires help cheatgrass expand its range.Natural resource managers attempt to remove cheatgrass and re-establish native plants after fires occur.PREVIQUS1 of 25NEXTSign outINTL 9 10:17&back74.

SCIENTIFIC INQUIRY An ecologist studying desert plantsperformed the following experiment. She staked out twoidentical plots, containing sagebrush plants and small annualwildflowers. She found the same five wildflower species inroughly equal numbers on both plots. She then enclosed oneplot with a fence to keep out kangaroo rats, the most commongrain-eaters of the area. After two years, four of the wildflowerspecies were no longer present in the fenced plot, but onespecies had become much more abundant. The control plothad not changed in species diversity. Using the principles ofcommunity ecology, propose a hypothesis to explain her results.What additional evidence would support your hypothesis?
