The correct Answer is:
To answer the question "How many muscles work together to move a bone?", we can follow these steps: 1. **Understanding Muscle Movement**: Muscles work in pairs to create movement. When one muscle contracts (shortens), the other muscle in the pair relaxes (lengthens). This coordinated action allows for the movement of bones. 2. **Identifying the Pair**: For any given movement, such as lifting an object, two muscles are typically involved. One muscle pulls the bone in one direction while the other muscle allows the bone to return to its original position by relaxing. 3. **Example of Muscle Action**: Consider the action of lifting a dumbbell. In this case, the bicep muscle contracts to lift the dumbbell, while the tricep muscle relaxes. When lowering the dumbbell, the tricep contracts to lower the weight, and the bicep relaxes. 4. **Conclusion**: Therefore, to move a bone, two muscles work together. This means that the correct answer to the question is **2 muscles**.
