A. Photosynthesis B. Digestion C. Circulation D. Excretion 相关知识点: 试题来源: 解析 C。本题考查与呼吸作用密切相关的过程。呼吸作用与血液循环密切相关,呼吸为血液提供氧气,血液将氧气运输到身体各处。选项 A 光合作用与呼吸作用不同;选项 B 消化与呼吸作用关系不大;选项 D 排泄与呼吸作用没有紧密联系。
Yeast is often used in the process of ___. A. photosynthesis B. respiration C. fermentation D. digestion 相关知识点: 试题来源: 解析 C。酵母经常用于发酵过程;“photosynthesis”是光合作用;“respiration”是呼吸作用;“digestion”是消化。反馈
A. photosynthesis B. respiration C. evaporation D. condensation 相关知识点: 试题来源: 解析 A。解析:在科学学科中,植物制造食物的过程被称为光合作用,photosynthesis这个单词就是光合作用的意思。respiration是呼吸作用,evaporation是蒸发,condensation是凝结,都不符合题意。反馈...
A. Respiration B. Photosynthesis C. Combustion D. Decomposition 相关知识点: 试题来源: 解析 B。解析:在碳循环中,第一步是光合作用。植物通过光合作用从大气中吸收二氧化碳,这是碳进入生物群落的开始。呼吸作用是碳返回大气的途径之一,选项A错误。燃烧是碳释放到大气的另一种方式,不是第一步,选项C错误。分解...
Summary• Gas exchange, fluorescence, western blot and chemical composition analyses were combined to assess if three functional groups (forbs, grasses and evergreen trees/shrubs) differed in acclimation of leaf respiration (R) and photosynthesis (A) to a range of growth temperatures (7, 14,...
The process of cell division is called ___. A. photosynthesis B. respiration C. mitosis D. digestion 相关知识点: 试题来源: 解析 C。细胞分裂的过程叫做有丝分裂(mitosis)。光合作用是制造有机物的过程,呼吸作用是消耗氧气产生能量的过程,消化是食物在体内分解的过程。反馈...
The main function of chloroplast is ___. A. respiration B. storage C. photosynthesis D. reproduction 相关知识点: 试题来源: 解析 C。叶绿体的主要功能是光合作用。呼吸作用主要在线粒体进行;存储不是叶绿体的主要功能;繁殖不是叶绿体的主要功能。

In the broadest sense, photosynthesis and cellular respiration are very similar. Though they are used by different organisms, both processes are used to create energy molecules. However, the two processes are actually quite different when you look closely....
This process creates a balance on Earth, in which the carbon dioxide produced by breathing organisms as they consume oxygen in respiration is converted back into oxygen by plants, algae and bacteria. Anoxygenic photosynthesis, meanwhile, uses electron donors that are not water and the process does...
