Question

Which of the following adaptations would you expect to find in bacteria that inhabits the geyser of Yellowstone National Park where temperatures can reach 158 F? 21 A. B. C. D. E. Higher concentration of phospholipids with short phospholipid tails Higher concentration of phospholipids with saturated fatty acids Higher concentration of phospholipids with unsaturated fatty acids Higher concentration of triglycerides with unsaturated fatty acids All of the adaptations listed that decrease viscosity

Explanation / Answer

hyperthermophiles (organisms living at high temperatures) have membranes dense in saturated fatty acids to keep the membrane soild and intact. they have way more trans-fatty acids in their cell wall along with phospholipids. for example - olive oil is a liquid at room temperature because it has more cis-fatty acids whereas butter has more saturated trans-fatty acids thats why it is solid at room temperature.

the answer is B.
