Double Jeopardy. All answers must be written down within 1 full minute.
A Bacterium lives on Mr. De Los Santos' plant in room 408. It has a cell membrane with 30% saturated phospholipids, 30 % unsaturated phospholipids, and 40% cholesterol. If this bacterium wanted to adapt to a hot desert environment, how would its cell membrane composition need to change? (Would anything increase? Would anything decrease.)
Unsaturated would decrease, Saturated would increase. (Cholesterol would decrease is also accepted.)
