Answer:
Uracil
Explanation:
In DNA, guanine pairs with cytosine and adenine pairs with thymine. In RNA, thymine changes into uracil.
Plants take in carbon dioxide and release oxygen gas during the process of photosynthesis.
Hope this helps (:
During active transport proteins powered by ATP move substances up a concentration gradient. During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
The process is decomposition.
Decomposition is a process by which organic substances, like leaves, are broken down into simpler matter. A lot of different types of organisms, called the decomposers, will consume the organic substances(like dead plants, dead animals) and continue an essential part of the nutrient cycle. This is important for recycling the organic matter that occupies space in the biosphere.
Answer:
ATP and NADPH
Explanation:
The Calvin cycle uses the reducing powers ATP and NADPH from the light dependent reactions to produce sugars for the plant to use.
