People plant a great number of young trees in the mountains.When the trees grow big and tall enough, they are cut down by workers and carried out of the mountains to the paper mill where fine paper is made from wood.Then it is taken to every corner of the country and used for differe...
What gases do plants use in photosynthesis? What kind of reaction is photosynthesis? The energy in glucose cannot be released by what system in photosynthesis The oxygen released in photosynthesis comes from? What are the raw materials for photosynthesis? What inputs are required for photosynthesis...
Without doing any diagram, explain the electron transport system (ETS) and oxidative phosphorylation. Focus on the substrates and products. What goes in? What comes out? What do electrons have to do with the Krebs cycle? What is the role of oxygen in the...
Plants, algae, and some types of bacteria use photosynthesis to create energy. A large percentage of the Earth’s oxygen comes from phytoplankton in the oceans, which contain chlorophyll and use photosynthesis to create energy. What is chlorophyll? Chlorophyll is a green pigment which absorbs energ...
There is 40 sun winter comes, there is less water in the air. Because of this, photosynth leaves stop producing chlorophyll, so plants stop producing food. 41disappears, other colors such as yellow and orange come out on the leaves fact, these colors are 42 there and they are nearly ...
5.【答案】When the roots and leaves of a tree are fully grown, the tree can then produce its own food and also provide oxygen into the atmosphere through a process called photosynthesis.【解析】本题主要是从文章中找信息。题目问的是树是怎么生存和生长的。结合全文,发现于第三大部分——How ...
Scientists now think that a large proportion of these molecules came from outside planet Earth. Comets and asteroids could be the missing links of a long chain.科学家们现在认为，这些分子中有很大一部分来自地球以外的星球。彗星和小行星可能是生命的长链中缺失的环节。The chain began with the simple ...
In autumn, days become shorter and shorter. There is___sunshine for plants. When winter comes, there is less water in the air. Because of this, photosynthesis slows down. Then leaves stop producing chlorophyll, so plants stop producing food.___the green chlorophyll disappears, other colors...
way. Though plants use their roots to pull water and some nutrients from soil, the majority of plants' energy comes from the sun. Plants are able to convert sunlight into usable energy, in the form of glucose, due to the structure of their cells and a process called photosynthesis. ...
Photosynthesis is a chemical reaction that makes life on Earth possible. In this process, autotrophs, which are plants and algae, are able to directly capture the sun's energy and use it to make their own food and also provide food for other living things....
