This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat. Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on faroff sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.large amounts of greenhouse gases enter the atmosphereB.releasedD.故選A。故選B。 Millipedes (千足蟲(chóng))giving out purple ink to make itself invisible to predatorsC. （2）考查細(xì)節(jié)理解。眼睛，并在攻擊者身上留下可怕的氣味。 Why does time seem to fly by faster as we get old?

Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day. Those surprising results appear in the journal Scientific Reports.But iridescence also shows up in situations where reproduction is not an issue. So what we are studying now is whether natural selection imposed by predation(捕食行為) could explain the occurrence of iridescence in prey animals. brilliantly changeable or metallic colors are among the strongest factors in an animal39。eye view.（1）According to the passage, iridescence is not made use of by animals to ________.
