Answer;
Carbon
Explanation;
-The large diversity of shapes of biological molecules is possible because of the extensive presence of carbon in the molecules.
-The major classes of biological molecules that are important for all living things are carbohydrates, lipids, proteins, and nucleic acids. These molecules differ in structure and function, in part, because of different functional groups.
All organic molecules contain carbon atoms. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.
-Carbon qualifies as the foundation element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
