Without it,3 on our planet would be very low.Plants use the sunlight and take up the CO, in the atmosphere to produce energy and oxygen.This 4 is called photosynthesis.The gas is 5 produced when fossil fuels are burned. Carbon dioxide that has been stored for millions of years in coal...
Thus, the food chain on Earth is born! With a sudden influx of glucose comes animals (including us humans), who eat photosynthetic organisms as well as the carbon stored within them. As this food is digested, the glucose is then oxidized through respiration, which returns carbon dioxide back...
Justwhere(= to what situation or final argument) is all this leading us? 这一切到底是要将我们引向何处? 牛津词典 It's one of the few countrieswherepeople drive on the left. 这是为数不多的几个靠左行驶的国家之一。 牛津词典 We then moved to Paris,wherewe lived for six years. ...
Bioluminescence(生物发光) is a natural phenomenon wherein(在其中) a chemical reaction within an organism's body produces light. It can be found in many places in nature-fireflies, some mushrooms-but mostly in the deep sea.Recently, Rambouillet, a small historic French town, has teamed up with...

It makes some of the town's public light up in the cool blue of bioluminescence.These bioluminescent bacteri a are stored in a seawater filled tube, giving the bacteri a room to float around and light up. The light provided by the bacteria is part of their natural metabolism, so ...
Geothermal energy is possible where there is what? Where is water stored? Where are most sediments and sedimentary rocks found? What are the main resources of Easter Island? Is shale gas a renewable resource? Where are carbon dioxide and oxygen found in the biosphere?
on the anode layer; the control grid for controlling the electron emission; the insulated support wall and auxiliary gettering element; the back glass panel is arranged with side ballast structure for adjusting the current direction of the cathode of carbon nanometer tube and adjusting the ...
Also, bioluminescence is not very bright compared to electrical lighting, though they have improved the light intensity(在用生物发光照亮世界的路上,你必须给细菌喂食,并在它们生长的过程中加水。这可不容易。这种现象将非常依赖于温度,我怀疑它在冬天会起作用。此外,生物发光与电照明相比不是很亮,尽管它们...
What are the major carbon sources on earth? In the Earth's crust, the most abundant element is at about % when rounded to the nearest whole percent. The second most abundant element is at about when rounded to the nearest whole percent. ...
