Question

Assume that a single layer of phospholipids coat the water in a beaker. which part of the phospholipid molecule will face the air?

a. the phosphate groups
b. the hydrocarbon tails
c. the phospholipids would dissolve and not form a membrane coat
d. both heads and tails as the molecules are amphipathic and will lie sideways
