Why is carbon so important to living organisms? Answer of the following question. Explain how human activities have impacted the water cycle and the potential consequences for Earth. Explain how water is recycled by the hydrologic cycle and how human activities can in...
4 Explain why it is important for humans to carry out conservation of fossil fuels and water supplies. 相关知识点: 试题来源: 解析 fossil fuels:they are non-renewable / will eventually run out;if used less it would result in:less carbon dioxide released from burning;less global warming;(so ...
Why are combustion reactions of fossil fuels so exothermic? Why are carbon atoms important in organic molecules? How does methane act as a greenhouse gas? Why do fatty acid come in chains of even-numbered hydrocarbons? Why is carbon the backbone of organic chemistry?
aThe excellent heat transfer in a fluidized bed, the low residence time of the monomers, and the low temperature gradient in the bed explain why so few side products and so little carbon black is formed. 优秀热传递在流化床,单体的低居住时间和低温梯度在床解释为什么那么少量副产品和那么一点炭黑...
The resulting mean upwelling determines large-scale oceanic circulation properties like heat and carbon transport. In the ocean interior, this turbulent mixing is caused mainly by breaking internal waves: generated predominantly by winds and tides, these waves interact nonlinearly, transferring energy down...
They take a gas called carbon dioxide (CO2) from the air. Plants use sunlight to turn water and CO2 into glucose. Glucose is a kind of sugar. Plants use glucose as food for energy to grow. The way plants turn water and CO2 into glucose is called photosynthesis. That means “putting ...
During its lifetime, a typical energy-saving lamp will stop about a tonne of carbon dioxide from entering the atmosphere and pay for itself many times over. [2] So it's good for your pocket and kind to the Earth as well. There are two quite different kinds: CFLs (compact fluorescent ...
ALDH then quickly diffuses that toxin, transforming it into something that can be broken down into water and carbon dioxide. But if what happens in lab dishes also occurs in the body, quercetin may cause acetaldehyde to accumulate. High levels of the toxin in the body can cause flushing, ...
Nuclear plants produce much lower carbon emissions than fossil fuel plants (coal, oil, and natural gas). [3] It's much more efficient to release energy by smashing atoms apart than by "burning them" (releasing energy through the chemical reaction we call combustion). That's why nuclear plan...
