Question 15 options:

one layer of phospholipids, through which proteins freely move

one layer of phospholipids, which are laid out end-to-end, with a hydrophobic tail touching a hydrophilic head

two layers of phospholipids, each of which has its hydrophilic side turned inward

two layers of phospholipids, with their polar hydrophilic heads facing away from each other

Answer:

The correct option is D. two layers of phospholipids, with their polar hydrophilic heads facing away from each other

Explanation:

The cell membrane is made up of two layers of phospholipids. The structure of phospholipids comprises of a hydrophobic tail which is made up of fatty acids and a hydrophilic head that is made up of phosphate. The structure of a cell membrane contains two fatty acid tails.

As the tail is hydrophobic, hence it is shielded and located inwards. The hydrophilic heads are located outwards in opposite directions.
