The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for an example of an aquatic annelid that possesses lateral appendages known as parapodia, which assist in swimming. 2. **Identifying Aquatic Annelids**: Aquatic annelids are segmented worms that live in water. They typically have specialized structures for locomotion. 3. **Defining Parapodia**: Parapodia are lateral appendages found in certain annelids, particularly in polychaetes, which are a class of annelids. These structures aid in swimming and movement. 4. **Evaluating the Options**: The options provided need to be assessed to find which one represents an aquatic annelid with parapodia: - **Option 1: Nereis** - This is a well-known genus of aquatic annelids that possess parapodia. - **Option 2: Parityma** - This is a terrestrial annelid, so it does not fit the criteria. - **Option 3: Herudinaria** - This is also a type of annelid (specifically a leech) that lacks parapodia. - **Option 4: Both Nereis and Herudinaria** - Since Herudinaria does not have parapodia, this option is incorrect. 5. **Conclusion**: Based on the evaluation, the correct answer is **Nereis**, as it is an aquatic annelid that possesses parapodia for swimming. **Final Answer**: Aquatic annelids like **Nereis** possess lateral appendages, parapodia, which help in swimming. ---

Two pipes of different diameters may be used to fill a swimming pool. The price with the larger diameter working alone can fill the swimming pool 1.25 times faster than the other pipe when it works alone. One hour after the larger pipe is opened, the smaller pipe is opened, and the swimming pool is filled 5 hours later. Which equation could be used to find the number of hours, x, it would take for the larger pipe to fill the pool working alone?
