Question

Staphylothermus marinus is an extremophile archaean that inhabits deep oceanic hydrothermal vents at temperatures near boiling. What would be the effect on this species' environmental requirements if the membrane lipid linkages were changed from ether bonds to ester bonds?a. It would require shallower depths with more light. b. It would only be able to survive farther away from the vents where there is less methane. c. It would only survive in freshwater habitats. d. It would only survive in areas farther away from the vents at lower temperatures. e. It would require anaerobic conditions such as those found in hot springs.

Answer 1

Answer: d) It would only survive in areas farther away from the vents at lower temperatures.

Explanation: Staphylothermus marinus is an anaerobic hetereotrophs that thrives in extremely hot environments with temperatures ranging from 85°c - 92°c when the nutrient concentration low and 98°c at a when the nutrient concentration is high thereby making them hyperthermophiles.
