Which of the Following Contribute to the Ability of Archaea

Question

Which of the following contribute to the ability of archaea to survive in extreme environments?
A) branched hydrocarbons with ether linkages
B) phospholipids with monounsaturated fatty acids
C) hopanoids
D) glycerols
E) both hopanoids and glycerols

Accepted Answer

Branched hydrocarbons with ether linkages are a unique feature of archaeal membranes that provide increased stability in extreme environments, such as high temperatures or extreme pH. Phospholipids with monounsaturated fatty acids and glycerols are found in bacterial and eukaryotic membranes, while hopanoids are found in bacterial membranes. Therefore, choices B, C, D, and E are not correct.
