Answer

To determine the number of moulting events in a cockroach after hatching and during its development into a complete animal, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Life Cycle of a Cockroach**:
- The life cycle of a cockroach consists of three main stages: eggs, nymph, and adult.

2. **Identify the Nymph Stage**:
- After hatching, the cockroach enters the nymph stage. This stage is crucial for growth and development.

3. **Recognize the Process of Moulting**:
- Moulting, also known as ecdysis, is the process where the nymph sheds its exoskeleton to grow. This is a gradual process that occurs multiple times.

4. **Determine the Number of Moults**:
- It is noted that a nymph undergoes approximately 10 to 13 moults before it becomes a fully grown adult cockroach.

5. **Conclude the Answer**:
- Therefore, the number of moulting events that a cockroach undergoes after hatching and during its development into a complete animal is more than 10.

### Final Answer:
The number of moulting in cockroaches after hatching and development of a complete animal is approximately 10 to 13 times.
