<span>Ribonucleic acid (RNA) occurs
primarily as single strands, often giving rise to single polynucleotide
structures. RNA is a polymeric molecule
that is responsible for the regulation, coding, decoding and expression of
genes. Each nucleotide has a ribose sugar attached to the carbon, a base that
is composed of purines and pyrimidines, a negatively charge phosphate groups
and a hydroxyl group which causes helix to mostly adopt the A-form geometry.</span>

Answer:
1, Planting trees
2. Actions that reduce carbon dioxide emission
Explanation:
Ally can reduce the amount of carbon dioxide in the atmosphere in two ways
1. By planting trees or reforestation
Trees generally act as a sink for carbon through photosynthesis. Hence, planting more trees means that more carbon dioxide in the atmosphere will become fixed into the trees leading to the reduction of the gas in the atmosphere.
2. Reducing emission
To further reduce the amount of carbon dioxide in the atmosphere, the rate of emission of the gas has to be reduced. Actions such as the burning of vegetation and fossil fuels need to be reduced because they increase the emission of carbon dioxide gas into the atmosphere. The actions can be substituted for less or no carbon dioxide emitting alternatives.
<em>When less carbon dioxide is emitted into the atmosphere and more is being fixed into trees, the overall concentration of the gas in the atmosphere will reduce greatly with time.</em>
