Q. Some hyperthermophilic organisms that grow in highly acidic (pH2) habitats belong to the two groups
A) Liverworts and yeasts
B) Eubacteria and archaea
C) Cyanobacteria and diatoms
D) Protists and mosses
Explanation
[Solution from source] Only prokaryotes tolerate the combination of very high temperature and very low pH; archaebacteria such as thermoacidophiles live in hot acidic springs, and some eubacteria also survive there. Eukaryotic groups like mosses, liverworts, yeasts and diatoms cannot survive such extreme conditions. Answer (2).
