Answer

To determine how much blood a single hookworm sucks, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Hookworm's Feeding Mechanism**:
- Hookworms attach to the intestinal wall of their host (like dogs) and suck blood as they feed.
- They perform a high number of suction actions per minute, which contributes to the amount of blood they can ingest.

2. **Suction Rate**:
- According to Welles (1931), hookworms can perform between 120 to 150 suctions per minute. This indicates a very active feeding process.

3. **Calculating Daily Blood Intake**:
- The study observed that the amount of blood ingested by a single hookworm over a day was calculated based on the number of red blood cells collected in a specific time frame (20 minutes).
- It was found that the total blood intake per day was approximately 0.8 ml.

4. **Conclusion**:
- Based on the observations and calculations, the amount of blood a single hookworm sucks in one day is determined to be **0.8 ml**.

### Final Answer:
A single hookworm sucks **0.8 ml** of blood.
