To fill in the missing information in the table, let's first understand the two categories: Carbohydrates and Proteins (Nucleic Acids). From fundamental knowledge in biochemistry:
1. Elements in Molecules:
- Carbohydrates are composed of carbon, hydrogen, and oxygen.
- Proteins are composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
2. Building Blocks:
- The building blocks of carbohydrates are monosaccharides (simple sugars like glucose).
- The building blocks of proteins are amino acids.
Given this knowledge, let's fill in the missing parts of the table:
- A: Carbohydrates are composed of carbon, hydrogen, and oxygen.
- B: Proteins contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
- C: The building blocks of carbohydrates are monosaccharides.
- D: The building blocks of carbohydrates are monosaccharides.
- E: The building blocks of proteins are amino acids.
So, the completed table should look like this:
\begin{tabular}{|l|c|l|c|}
