And also. like people, the response to that stress can determine success Bad environmental conditions, such as drought, flood, heat and other stresses, affect yields(产量) more than crop pests and diseases.“We are trying to find a way to equip plants with the ability to tolerate environmental stress and maintain high yields”said Stephen Howell, a professor of genetics and cell biology. “Plant cells produce proteins(蛋白质)and ship them to different parts of the cell. Under normal conditions,these proteins are folded into their normal, healthy structures as they are produced. When a plant is under stress, its cells produce poorly folded or unfolded proteins. Then a built-in system senses this and sets off an alarm in the cell,” said Howell. In response to the alarm, another protein(IRE1)starts working and creates a different process which activates(激活) the stress response genes whose products bring about defensive measures that help the plant survive. “As it turns out, responses that are activated under stressful conditions actually inhibit the growth of plants,” said Howell. “This allows them to preserve their energy to survive the stressful conditions.” “For plants in the wild, this response is a help for survival”, he said. In production of agricultural crops, however, this response reduces yields. “You don't want crop plants to stop growing, Howell said. “You want them to continue to grow and produce more even though they are under stress.” “With the new understanding of this stress response, the next step may be to silence the alarm system”, said Howell.“What may be important is to disable some of these stress responses.That may make the plant more productive under stressful conditions.” 1.

C.By making the alarm system stop working D.By making the alarm system respond quickly B 主题语境:人与社会--社会热点 语篇类型:说明文 建议用时:8 (2021辽宁阜新高二上12月月考,蝓) Organic food is very popularIt is also expensive.

The following are my reasons. First of all, we should do everything in our power to protect our delicate environment.Organic farming,with no chemical fertilizers, can keep the soil rich. As a result, it's sure that organic farming is good to the environment. With more and more people diagnosed with cancer, we should pay more attention to our food. Organic farming produces food full of minerals and vitamins, which is nutritious. The better food we eat, the less likely we are to develop diseases. Lastly, all of us know that food produced in the traditional chemical way tastes bad. However, organic food is more delicious, which helps us have a good appetite. In a word,I think organic farming is better. 提升篇 In my opinion, organic farming is preferable to chemical farming because of its significant advantages over the latter. Details are as follows In the first place, so delicate is the environment that we should do everything in our power to protect it. Intended to keep the soil rich, organic farming, which is free of chemical fertilizers, is undoubtedly friendly to the environment. With the number of people diagnosed with cancer on the rise, we are supposed to attach more attention to what we eat. Rich in minerals and vitamins, organic food guarantees us the essential nutrition as well as reducing the likelihood of potential serious disease. It is widely known that food produced from chemical farming tastes flavourless while organic farming can secure the natural flavour of the food, thus stimulating our appetite. In conclusion with all these factors taken into account, preference should be given to organic farming. ( 1 ) 学科网（北京）股份有限公司 $$
