Which domain includes prokaryotic organisms that can live in extreme conditions? (2 points)

archaea
bacteria
eukarya
prokarya

The correct answer is -

Archaea.

Explanation:

Archaea is one three domains of life forms (according to Carl Woese three domain system of classification) that includes prokaryotic organisms that survive under extremely harsh environmental conditions such as hotsprings, volcanic eruption, highly acidic conditions etc.

These organsisms are therefore also known as extremophiles.

Example - Methanogens.

Thus, Archaea is the right answer.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
