The correct Answer is:
To solve the question regarding which type of bacteria differ from other bacteria in having a different cell wall structure that allows them to survive in extreme conditions, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Extremophiles**: - Extremophiles are organisms that thrive in extreme environmental conditions. This includes high temperatures, extreme acidity, or high salinity. 2. **Identifying the Options**: - The options provided are: - A) Methanogens - B) Thermoacidophiles - C) Cyanobacteria - D) Both A and B 3. **Analyzing Methanogens**: - Methanogens are a type of archaea that produce methane and can survive in anaerobic (no oxygen) environments. - Their cell wall is made of pseudo-peptidoglycan, which is different from the typical peptidoglycan found in many bacteria. 4. **Analyzing Thermoacidophiles**: - Thermoacidophiles are organisms that can survive in high temperatures (around 95 degrees Celsius) and low pH (acidic conditions). - They also have unique cell wall structures that allow them to withstand these extreme conditions. 5. **Analyzing Cyanobacteria**: - Cyanobacteria are photosynthetic bacteria that do not specifically thrive in extreme conditions. They can survive in a variety of environments but are not classified as extremophiles. 6. **Conclusion**: - Since both methanogens and thermoacidophiles have unique cell wall structures that allow them to survive in extreme conditions, the correct answer is **D) Both A and B**. ### Final Answer: **D) Both A and B**
