Please help..Which of the following best explains why a cell's plasma membrane is composed of two layers of phospholipids rather than just a single layer?
Having two oppositely oriented layers of phospholipids allows only the hydrophilic heads to interact with water inside and outside of the cell
B
Having two oppositely oriented layers of phospholipids allows the hydrophilic heads to repel water both inside and outside of the cells
Having two identically oriented layers of phospholipids gives cells more protection from the exterior environment than just a single layer would.
Having two identically oriented layers of phospholipids allows for the production of vacuoles while still maintaining a protective barrier.
