Archaebacteria can survive at which of the following temperature(˚C)?
Correct answer: C. 120˚C
- A. 300˚C
- B. 150˚C
- C. 120˚C
- D. 200˚C
Explanation
Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria, but this term has fallen out of use. Archaebacteria (Thermophiles) are ancient forms of bacteria found in hot water springs and deep-sea hydrothermal vents. They are able to survive in high temperatures, up to 120 degrees, because their bodies have adapted to such environmental conditions.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
