Question

95% of organic macromolecules are made up of the following elements: (1 point) carbon, helium, nitrogen, potassium carbon, hydrogen, phosphorous, boron carbon, hydrogen, nitrogen, oxygen

Explanation:

Step1: Recall organic macromolecule elements

Organic macromolecules like proteins, lipids, carbohydrates and nucleic acids (DNA/RNA) mainly consist of carbon - based compounds.

Step2: Analyze element composition

Carbon is a key element in all organic compounds. Hydrogen is also present in large amounts. Nitrogen is in proteins and nucleic acids, and oxygen is in all these macromolecules.

Answer:

carbon, hydrogen, nitrogen, oxygen
