D. 2000

Answer

To determine the number of uriniferous tubules (nephrons) in the kidney of a frog, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Frog Kidney**:
- The kidney of a frog is composed of numerous microscopic tubes known as uriniferous tubules or nephrons.

2. **Identifying the Function of Nephrons**:
- Each nephron serves as the structural and functional unit of the kidney, responsible for filtering blood and producing urine.

3. **Counting the Nephrons**:
- It is important to know the approximate number of nephrons present in a frog's kidney. Research indicates that a frog's kidney contains about 2,000 nephrons.

4. **Evaluating the Options**:
- Given the options: numerous, 10,000, 5,000, and 2,000, we can eliminate the first three options based on the specific count we have established.

5. **Conclusion**:
- The correct answer is that there are approximately **2,000 uriniferous tubules** (nephrons) in the kidney of a frog.

### Final Answer:
The number of uriniferous tubules in a kidney of a frog is **2,000**.
