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>
The phenotypes of snapdragons of F1 generation had pink flowers only.
Explanation:
The crossing of snapdragon with red flowers and white flowers as well led to the production of F1 offspring of hybrid quality having pink flowers only. This F1 phenotype under goes pollination and results in F2 phenotype with a ratio of 1 red, 1 white and 2 pink flower.
This is incomplete dominance as the phenotypes of parental plant, as in the white and red flowered plant reappear in the F2 generation.
