Oil is being obtained from the Arctic region, and this can cause environmental problems when there are spills since normally toxins take much longer to be degraded in colder temperatures. There are two good possible strategies to help clean up oil spills in the Arctic using bioremediation. One idea would be evolving oil-eating microbes that are found in warmer temperatures like the Gulf of Mexico to live in the Arctic. Another would be to genetically engineer the petroleum-degrading genes into psychrophilic organisms. 1st attempt Part 1 (1 point)See Hint What kind of cellular changes would be expected in oil-eating microbes moved from a warmer environment to the Arctic? Choose one: A. increased cholesterol in the membranes and increased glycogen storage for nutrient availability B. increased cell wall thickness to act as a blanket against the cold and decreased movement to save energy for other important functions C. increased cellular movement to keep the temperature higher and increased pore production to allow ice crystals to be pumped out of the cell D. increased unsaturated fatty acids in membrane phospholipids and development of trehalose being used as a cryoprotectant
