Even photosynthesis, the way plants convert energy into food, is not as efficient as our method. Moreover, the production of plant-based proteins can't be scaled up enough with the resources the planet has to match the rapidly increasing need for protein. It takes just a fraction of the ...
GA (rummaging in the gearbox): What else have we got? (turning to TA) Hey, you! Are you already sedated from turpentine sniffing, or what? Can you become a little more helpful and get engaged here, you junkie? If you would not have wasted all our green colour, we would have ...
Photosynthesis and cellular respiration are very closely linked processes. Carbon dioxide and water, the what of photosynthesis, are the what of cellular respiration? What is cellular respiration? Explain in details. Do catabolic processes onl...
This first stage produces simple molecules, which can then recombine to make more complex molecules if this astonishing experiment is successful. What we're going to do now is warm the system a little to see what the ice does.第一步产生简单的分子，如果这个惊人的实验成功的话，这些简单的分子就...
Because plants in the tropics survived, something else must have caused dinosaur extinction in these areas. One suggestion is that placental mammals (mammals that give live birth and have a placenta) became abundant in the mountains, because they no longer competed with dinosaurs. Later, the ...
Plants take in water through their roots, and green ones use it in photosynthesis, which is how they create sugar for food. (You can learn more about the process of photosynthesis in How the Earth Works.) Plants also need water to support themselves. Pressure from the process of osmosis -...
Lipids are made up of fatty acids and what else? When fructose and glucose are bonded together they form what? How is sucrose produced from the end products of photosynthesis? Which macromolecules store energy? The ATP made during glycolysis is generated by what?
A second Hector for his grim aspect,And large proportion of his strong-knit limbs. Branch To separate (something) into branches. Limb A thing or person regarded as a part or member of, or attachment to, something else. That little limb of the devil has cheated the gallows. Branch To emb...
A. the food for trees is made from the water and sugar in the soil B. photosynthesis can't take place at night C. photosynthesis can take place at any time D. trees help little in improving the air conditions 66. According to the passage, where should more trees be planted?
Argentinosaurus is one of the largest dinosaurs ever discovered. You can see what its skeleton looked like at Fernbank Museum of Natural History in Atlanta, Ga. The Argentinosaurus skeleton in the museum's great hall dwarfs everything else in the room. From nose to tail, it's more than 120...
