Geologist measure the number of Carbon 15 dating to calculate the age of a specimen
<u>Answer</u>:
The main elements that are present in proteins, carbohydrates, lipids, and nucleic acids are
B)carbon and hydrogen
C) oxygen and nitrogen
<u>Explanation</u>:
In common they have hydrogen, carbon, oxygen as well as nitrogen. Nitrogen are the reduced form so as the major component among the three others. It helps in the formation of the proteins and the polypeptides, DNA and RNA also in the formation of polymers of the amino sugars. Proteins are made from the carbon, hydrogen, oxygen, as well as nitrogen. The nucleic acid like DNA and RNA has carbon, hydrogen, oxygen, nitrogen and the phosphorus in it. The body also requires small amount of calcium, potassium and sulphur for the proper functioning of the muscles as well as the nerves.
The main difference is in the presence of a carbon atom; organic compounds will contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost all inorganic compounds do not contain either of those two atoms. ... Meanwhile, inorganic compounds include the salts, metals, and other elemental compounds.
