Answer

To arrange the periods of the Paleozoic era in ascending order on the geological time scale, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Periods of the Paleozoic Era**:
The Paleozoic era is divided into six main periods:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian

2. **Arrange the Periods in Ascending Order**:
The correct order of the periods from the earliest to the latest is:
- **1st: Cambrian**
- **2nd: Ordovician**
- **3rd: Silurian**
- **4th: Devonian**
- **5th: Carboniferous**
- **6th: Permian**

3. **Final Arrangement**:
Therefore, the periods of the Paleozoic era arranged in ascending order are:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian
