Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
Explanation:
Photosynthesis manufactures sugar from carbon dioxide from respiration and water using sunlight as the source of energy. Carbon dioxide diffuses through the stomata from the atmosphere and releases oxygen which is used in cellular respiration to break down food forming carbon dioxide, energy and water.
After the generation of the RNA would indicate that
C. It is controlled after transcription
Now it could also be translation (because that is after the protein is made) - but because your question asks specifically after the RNA is formed (that process is called transcription) that would indicate that your answer is C.
The main reason that most farmers use stem cuttings rather than just planting a seed is that a tree's genetic variation will occur. The seeds of many fruit trees tend to vary differently from the parent, because seeds themselves are produced by sexual reproduction (i.e they receive genes from a male and female to form). As they are a cross from two sets of genes, many fruit trees are not “true to seed”. Their seeds will produce a generally different variety of tree from the parent. When using stem cuttings, it's almost like a cloning process.
Uracil is found in RNA and not DNA. DNA instead has thymine
