To determine the answer to this question, we can recall some basic knowledge about biomolecules. Biomolecules are the building blocks of life and include carbohydrates, lipids, proteins, and nucleic acids. These molecules are composed of atoms, and we need to identify the common elements present in all biomolecules.
The correct answer is: carbon, hydrogen, nitrogen, and oxygen.
Explanation: Carbon is the central element in biomolecules, providing the structural backbone. Hydrogen is the most abundant element in biomolecules, usually bonded with carbon. Nitrogen is present in proteins and nucleic acids, while oxygen is found in carbohydrates, lipids, proteins, and nucleic acids. The presence of these four elements is a common characteristic shared by all biomolecules.
