Answer

### Step-by-Step Solution:

1. **Understanding Mutation**:
- Mutation refers to a change in the DNA sequence of an organism. This change can occur due to various factors, including damage to the DNA or errors during DNA replication.

2. **Definition of Mutation**:
- A mutation alters the genetic message or genetic material, which can affect the organism's traits and characteristics.

3. **Role of Mutagens**:
- Mutagens are agents or substances that can cause mutations by permanently altering the physical composition of DNA. These can be chemicals, radiation, or biological agents.

4. **Moody's Description of Mutation**:
- The scientist Moody described mutation as an "inheritable change in the germ plasm." This means that mutations can be passed on to the next generation if they occur in the reproductive cells.

5. **Moody's Analogy**:
- Moody referred to mutation as "shotgun." This analogy suggests that mutations can occur spontaneously and unpredictably, similar to how a shotgun disperses pellets in a wide area.

6. **Evaluating Options**:
- The options provided are:
- Factor
- Saltation
- Sport
- Shotgun
- Based on the explanation, the correct answer is "shotgun," as it aligns with Moody's description of mutation.

### Final Answer:
Moody describes mutation as "shotgun."
