根据“Trees get less sunlight, so photosynthesis slows down.”可知,秋天树叶停止产生绿色化学物质是因为阳光减少。故选B。 (4)题详解: 词句猜测题。根据“Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves turn ...
例如,“How does photosynthesis work?”(光合作用是如何进行的?) - 使用“why”:在研究科学原理或社会现象时,探究其背后的原因和机制。例如,“Why do plants need sunlight for photosynthesis?”(植物为什么需要阳光进行光合作用?) 3. **日常交流** - 使用“how”:在询问他人如何完成某项任务或了解他人的经验...
询问某个行为或事件的动机:“Why were you late for work?”(你为什么上班迟到了?) 三、答案类型 what 答案通常是描述性或定义性的,涉及具体细节或事实。例如:“What is photosynthesis?”(什么是光合作用?)“A process by which plants convert sunlight into energy.”(植物将阳光转化为能量的过程)。 why 答...
B. Photosynthesis allows plants to survive on land; without it, life would be restricted to aqueous environments What is photosynthesis and how does it work? What is photosynthesis? How does it work? What is the role of chloroplast in the process of photosynthesis in plants? What is ...
How does phytoplankton produce oxygen? Why do birds not move their eyes? Why do alveoli not stick together? What purpose does nitrogen serve in air? How does the eye work? Why is water split during photosynthesis? Why are the products of the light reaction of photosynthesis important?
1. Why are you so happy today? Because I got a promotion at work.（你今天为啥这么高兴？因为我工作上得到晋升啦。）。2. Why did you buy this dress? Because it looks really nice on me.（你为啥买这条裙子？因为我穿上它很好看。）。3. Why are you going to the supermarket? Because we'...
根据第三段"It branched away from having genetics that code for photosynthesis(光合作用) millions of years ago,and relies entirely upon its host —the vines for energy. (它在数百万年前就已经脱离了编码光合作用的基因,完全依赖于它的宿主——葡萄藤来获取能量。)"可知,Rafflesia是从它的宿主——葡萄...
However, it can only work like this for a short time because with the stomata shut, oxygen can easily reach toxic levels in the leaf. Too much oxygen in the leaf leads to a process called photorespiration, which is when the enzymes involved in photosynthesis wastefully bind to oxygen...
Some is used for photosynthesis and is temporarily stored in the biosphere in the form of plant and animal life. When plants die and are buried, some of the solar energy is stored in rocks, when we burn coal, oil, or natural gas, we release stored solar energy.The second most powerful...
How does the dark reaction of photosynthesis work? How is light energy harvested in photosynthesis? Explain. How would these factors affect the rate of photosynthesis? a. Temperatures exceed 50 C b. Light wavelength allows green light only c. Light levels are at maximum...
