Which type of bacteria can live in harsh conditions and are considered extremophils?
A
Archaebacteriqa
B
Eubacteria
C
Caperia
D
exempleria
Explanation: 

Detailed explanation-1: -Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.

Detailed explanation-2: -Extremophiles. Extremophiles are unicellular microbes (bacteria and archaea) that thrive in extreme environments. Many of these belong to archaea, which are considered to be an ancient bridge between bacteria and eukarya. They can be thermophilic, hyperthermophilic, acidophilic, and alkalophilics, etc.

Detailed explanation-3: -The bacteria Deinococcus radiodurans can live in extreme sircumstances. The most extreme extremophile that is known at the moment is the Deinococcus radiodurans. This microbe can survive extreme cold, drought, thin air and acid.

Detailed explanation-4: -Today we look at four types of extremophiles: thermophiles, psychrophiles, halophiles and acidophiles.
