本题对应本段第一句，原文说生物死后如果能快速沉淀并且隔绝氧气，软体组织保存的概率会增加，也就是说氧气的存在不利于化石的保存，所以 D 选项正确。选项 A 说含氧的环境增加了化石形成的概率，说法与原文矛盾；B 选项说含氧的环境导致细菌更多，但是原文第二句说缺氧的环境能减轻细菌的破坏作用，并不...
If you’ve had a checkup, a medical professional may have clipped a device to your finger to measure your oxygen saturation (SpO2) and pulse. Until last year, that was my only experience with such devices, but during the pandemic, I and many others purchased our own pulse oximeters to ...
There are many common conditions that can affect your lungs. Diseases or conditions of the lung fall mainly into two classes — those that make breathing harder and those that damage the lungs' ability to exchange carbon dioxide for oxygen. Diseases or conditions that influence the mechanics of ...
If you live far from the coast,you might think they don't.But life on this planet depends on the ocean.It covers almost three-quarters of the planet and holds 97 percent of Earth's water.The phytoplankton (浮游植物)that live on the oceans' surface produce half ...
Photosynthesis is the process that occurs in plants (chlorophyll) where the solar energy, through the water hydrolysis, is used for atmospheric carbon dioxide assimilation, resulting in the production of carbohydrate molecules and oxygen. The balanced general equation of this phenomenon, for C3 plants...
During the period of high-quality development in China, environmental regulations have been regarded as powerful exogenous forces, especially for accelerating the green transformation of the manufacturing industry. Treating the first implementation of cleaner production industry standard policies in 2003 as ...
11.According to paragraph 7, how do environments containing oxygen affect fossil preservation? A. They increase the probability that soft-tissued organisms will become fossils. B. They lead to more bacteria production. C. They slow the rate at which clay and silt are deposited. ...
on-board rockets and shuttles. NASA favored this method because the alkaline cell has high efficiency and a low operating temperature. However, because it’s highly susceptible to contamination, it requires pure hydrogen and oxygen. And it is unlikely to be commercialized because of the high cost...
