Which of the following best describes anaerobic bacteria? A) They can use oxygen but do not rely on it. B) They are found in various natural habitats. C) They require oxygen for growth. D) They cannot tolerate oxygen at all.
Understand the Problem
The question is asking to identify the best description of anaerobic bacteria from the provided options. We need to evaluate each option to determine which accurately describes the characteristics of anaerobic bacteria.
Answer
They cannot tolerate oxygen at all.
The final answer is D) They cannot tolerate oxygen at all.
Answer for screen readers
The final answer is D) They cannot tolerate oxygen at all.
More Information
Anaerobic bacteria cannot grow in the presence of oxygen as it is toxic to them. They rely on other substances to sustain their biological processes.
Tips
A common mistake is confusing anaerobic bacteria with facultative anaerobes, which can grow with or without oxygen.
