Question

rna and dna have nitrogenous bases, the base that is different from from dna, in rna, is adenine uracil guanine thymine the three elements found in all biomolecules (macromolecules) are: carbon, hydrogen, and nitrogen carbon, hydrogen, and sulfur carbon, hydrogen, and oxygen carbon, oxygen, and phosphorus

Explanation:

1. DNA contains adenine (A), thymine (T), guanine (G), and cytosine (C). RNA contains adenine (A), uracil (U), guanine (G), and cytosine (C). So uracil is the base that is different from DNA in RNA.
2. All biomolecules (macromolecules) such as carbohydrates, lipids, proteins, and nucleic - acids contain carbon, hydrogen, and oxygen.

Answer:

1. B. Uracil
2. C. Carbon, hydrogen, and oxygen
