Which of the Following Describe All Existing Bacteria

Question

Which of the following describe all existing bacteria?
A)pathogenic, omnipresent, morphologically diverse
B)extremophiles, tiny, abundant
C)tiny, ubiquitous, metabolically diverse
D)morphologically diverse, metabolically diverse, extremophiles

Accepted Answer

All existing bacteria are small in size, found everywhere, and have a wide range of metabolic capabilities. While some bacteria are pathogenic, not all bacteria fall into this category. Similarly, while some bacteria are extremophiles (able to survive in extreme environments), this is not true of all bacteria. Morphological diversity is also present but not universal among bacteria.
