The right option is A. hydrofluorocarbons
Hydrofluorocarbons are pollutants that are likely to be produced from air conditioning.
Hydrofluorocarbons (HFCs) are synthetic fluorinated strong greenhouse gases that are strongly accumulating in the atmosphere. Hydrofluorocarbons are mainly used as refrigerants. Hydrofluorocarbons are used to replace ozone depleting substances such as chlorofluorocarbons and hydrochlorofluorocarbons which are being phased out in air conditioning, refrigeration, foam blowing agents, and solvents. Hydrofluorocarbons are responsible for about 20% of climate pollution by 2050
The synthesis<span> of </span>proteins<span> takes two step, transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell's nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize </span>proteins<span>.</span>
Some plants also have large leaves to soak up nutrients and water, very helpful in this biome since it rains a lot. - Having some needles cased in wax, withstand cold temperatures and losing water from their leaves. - Having thin bark and shallow roots enables trees to withstand fire.
Answer:
Carbohydrates can be described as biological molecules which are made up of carbon, hydrogen and oxygen.
Simple carbohydrates are known as monosaccharides. Example of monosaccharide includes glucose and fructose. Two molecules of monosaccharides can join to form disaccharides. Example of disaccharide includes maltose. When three or more monosaccharides join they form polymers known as polysaccharides. In this way, simple carbohydrates form larger molecules or polysaccharides. Examples of polysaccharides include starch, glycogen, cellulose etc.
