Question

Dr. Lange discovers a colony of bacteria living in an extremely acidic environment. While observing the colony, she finds that the bacteria are autotrophs. Which best describes the bacteria discovered by the scientist? They are probably archaebacteria because they are autotrophs. They are probably eubacteria because they are autotrophs. They are probably eubacteria because the colony lives in an extreme environment. They are probably archaebacteria because the colony lives in an extreme environment.

Answer 2

"They are probably archaebacteria because the colony lives in an extreme environment" best describes the bacteria discovered by the scientist.

Option: D

Step-by-step explanation:

Archaebacteria count as the organisms who prepare their food i.e autotroph. In their atmosphere, they produce their food from the raw materials including carbon, oxygen, hydrogen, metals and simple organic molecules like sugar. Many archaebacteria are present in extremely harsh conditions. These are also extremophiles.

The two finest-known classes of archaea are the crenarchaeotes and euryarchaeotes. This category includes most known thermophiles i.e the heat-lovers. They live most often in hot or acidic conditions. These can be identified, for an instance, in strongly acidic, hot sulfur springs at temperatures above 75 ° C.
