When these charged particles of cosmic rays collide with molecules in the upper atmosphere, they break up into smaller particles, muons. Traveling at the speed of light, muons can penetrate tens of meters into rocks and other matter on Earth’s surface. ln fact, they can pass through solid ...
just like the original experiment, except without the electricity.The the same mixture were water and gases, but he doesn't run electricity through it.But this time, no organic compounds were produced.So it seemed that electricity was a critical part of creating the organic molecules in his or...
aIn addition, simple water-insoluble molecules can also be spread, but they usually favor the formation of crystallites or multilayers with one to several layers thickness 另外,可能也涂简单的水不溶性的分子,但他们通常倾向晶子或multilayers的形成于一个对几层数厚度[translate] ...
aphase separation cannot follow the polymerization kinetics because the time-scale for polymerization is smaller than that of phase separation due to the slower diffusion of LC molecules in highly viscous media. 因为时间表尺度为聚化那小于分相由于LC分子更加缓慢的扩散在高度黏媒介,分相不可能跟随聚化动...
These organic metabolites could, and probably do, include a number of different classes of organic compounds.Some are likely toxins, such as those released by the dinoflagellates (a species of plankton) during red tides, which inhibit growth of other photosynthetic organisms.In such cases, the pop...
the number of molecules of air affected by the sound-producing object c. the frequency of the sound wave d. the time it takes for a sound to reach the earThe sounds of a language convey meaning; words serve as symbols for action...
energy by the oxidation or reduction of inorganic sulfur or nitrogen molecules (Supplementary Fig.3). To further investigate the metabolic capacity of the novel Aratimonadetes genomes, we compared their predicted proteomes with a combination of functional databases and protein phylogenies. We manually ...
The foreign molecules that elicit a specific response of the immune system are called: A. pyrogens B. T helper lymphocytes C. B lymphocytes D. antigens E. antibodies All cells in the body can get infected, and when infected, a cell...
A simple yet accurate theoretical description of this cooperativity is lacking. From a general mechanochemical model that treats tropomyosin as a continuous beam, we show that cooperative interactions can be defined by two parameters: C, which specifies the number of neighboring molecules affected by ...
aRecently, a number of studies have revealed the behavior of Cd in rice, genetic diversity of Cd accumulation, quantitative trait loci controlling Cd accumulation and transporter molecules regulating Cd accumulation and distribution in rice. 最近,一定数量的研究在米在米显露了Cd行为, CD的储积,控制CD...
