Example of bacteria requiring low concentration of oxygen is__________?
Correct answer: A. Campylobactor
- A. Campylobactor
- B. spirocheta
- C. E-coli
- D. Pseudomonas
Explanation
Campylobacter is microaerophilic, meaning it grows best at an oxygen concentration below that of normal air. Students may choose Pseudomonas because it is strongly associated with aerobic respiration, but it generally does not require the low-oxygen conditions characteristic of microaerophiles.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
