In order to study a cell at lower temperatures,a researcher must artificially increase its membrane fluidity.What would be a reasonable strategy for increasing plasma membrane fluidity at low temperatures?
A)Decrease the composition of cholesterol in the plasma membrane
B)Increase the composition of phospholipids with saturated fatty acid chains
C)Decrease the composition of phospholipids with unsaturated fatty acid chains
D)Decrease the length of the phospholipid fatty acyl tail.
E)All of the above strategies are reasonable

Decreasing the length of the phospholipid fatty acyl tails increases membrane fluidity by reducing the van der Waals forces between the tails, making the membrane more fluid at lower temperatures.
