Which one of the following biomolecules will be different in different animals?

Options

A. Lipids
B. Vitamins
C. Carbohydrates
D. Proteins

Answer

**Step-by-Step Solution:**

1. **Understanding Biomolecules**: Begin by defining what biomolecules are. Biomolecules are organic molecules that are essential for life, and they include lipids, carbohydrates, proteins, and vitamins.

2. **Analyzing Lipids**: Consider the first biomolecule, lipids. Lipids serve important functions such as providing insulation and energy storage. However, their primary functions remain consistent across different animals. Therefore, lipids do not vary significantly between species.

3. **Examining Vitamins**: Next, look at vitamins. For example, vitamin A (retinol) is crucial for vision in all animals. The role of vitamins is generally conserved, meaning they perform the same functions across different species. Thus, vitamins do not differ significantly among animals.

4. **Considering Carbohydrates**: Now, evaluate carbohydrates. They serve as energy sources and storage molecules (like glycogen). While their roles are vital, the fundamental functions of carbohydrates do not vary greatly between animals. Hence, carbohydrates are also not the answer.

5. **Investigating Proteins**: Finally, analyze proteins. Proteins are synthesized based on the genetic material (DNA) of an organism. Since different species have different genetic codes, the types and functions of proteins can vary widely from one animal to another. This variability makes proteins the most diverse biomolecules among different animals.

6. **Conclusion**: Based on the analysis, the biomolecule that will be different in different animals is proteins.

**Final Answer**: Proteins are the biomolecules that will differ among different animals.
