Options

A. lons `lt` Lipids `lt` Carbohydrates `lt` Nucleic acid `lt` Proteins
B. Lipids `lt` lons `lt` Carbohydrates `lt` Nucleic acids `lt` Proteins
C. lons `lt` Carbohydrates `lt` Lipids `lt` Nucleic acids `lt` Proteins
D. lons`lt` Nucleic acids `lt` Carbohydrates `lt` Lipids `lt` Proteins

Answer

To solve the question regarding the increasing order of the average percentage composition of biomolecules in total cellular mass, we need to analyze the composition of various biomolecules in the human body. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Biomolecules and Their Percentages
We need to list the biomolecules mentioned in the question along with their average percentage composition of total cellular mass:
- **Ions**: Approximately 1%
- **Lipids**: Approximately 2%
- **Carbohydrates**: Approximately 3%
- **Nucleic Acids**: Approximately 5-7%
- **Proteins**: Approximately 10-15%
- **Water**: Approximately 70-90% (not included in the options)

### Step 2: Arrange the Biomolecules in Increasing Order
Now, we will arrange these biomolecules from the lowest to the highest percentage of total cellular mass:
1. **Ions**: 1%
2. **Lipids**: 2%
3. **Carbohydrates**: 3%
4. **Nucleic Acids**: 5-7%
5. **Proteins**: 10-15%

### Step 3: Verify the Options Provided
Now, we can check the provided options to see which one matches our arrangement:
- **Option 1**: Ions, Lipids, Carbohydrates, Nucleic Acids, Proteins (Correct)
- **Option 2**: Lipids, Ions, Carbohydrates, Nucleic Acids, Proteins (Incorrect)
- **Option 3**: Ions, Carbohydrates, Lipids, Nucleic Acids, Proteins (Incorrect)
- **Option 4**: Ions, Nucleic Acids, Lipids, Proteins (Incorrect)

### Conclusion
The correct order of biomolecules arranged in increasing order of their average percentage composition of total cellular mass is:
**Ions < Lipids < Carbohydrates < Nucleic Acids < Proteins**

### Final Answer
The correct answer is **Ions, Lipids, Carbohydrates, Nucleic Acids, Proteins**.
