Think about the bilayer arrangement of phospholipids in cell membranes.Now imagine if extracellular and intracellular fluids were made of oil instead of water.How would the phospholipids arrange themselves?
A)The hydrophilic heads would be oriented toward the middle,with hydrophobic tails pointing outward.
B)The hydrophobic heads would be oriented toward the oil,so outward;the hydrophilic tails would be pointed inward.
C)The hydrophobic tails would be oriented inward,while the hydrophilic heads would point outward.

In an oil-based environment, the hydrophilic (water-attracting) heads of phospholipids would avoid the oil by pointing inward, while the hydrophobic (water-repelling) tails would interact more favorably with the oil by pointing outward. This arrangement is opposite to that in a water-based environment.
