Question

Some hyperthermophilic organisms that grow in highly acidic (pH=2) habitats belong to the two groups:

• A. Liverworts and Yeasts
• B. Eubacteria and Archaea
• C. Cyanobacteria and Diatoms
• D. Protists and Mosses

Answer 1

The correct option is B

Explanation of the correct option:

1. Hyperthermophilic organisms have membranes resistant to adverse environmental conditions.
2. The hyperthermophilic organisms can survive in high temperatures in the range of about 70 - 120${}^{0}C$ .
3. Some of these organisms can also survive in low pH of about 2. These organisms are the archaebacteria and bacterial species.
4. These are prokaryotic organisms which can survive in extreme conditions.

​Explanation of the incorrect option:

Option A,C and D didnot satisfy the appropriate explanation of the given question.

Final answer: Some hyperthermophilic organisms that grow in highly acidic (pH=2) habitats belong to the two groups i.e. ; Cyanobacteria and Diatoms.
