The plasma membrane is a network of protein, carbohydrates, and lipids that protect the cell from the surrounding environment. The phospholipid bilayer regulates the transport of molecules into and out of the cell. Which characteristics of phospholipids' orientation facilitate their function in the cell? Select all that apply.
A
The inward-facing orientation of non-polar tails allows the bilayer to act as a barrier for charged and polar molecules entering and exiting the cell.

B
The inward-facing orientation of polar tails allows the bilayer to act as a barrier for charged and non-polar molecules entering and exiting the cell.

C
The outward-facing orientation of hydrophobic heads allows interactions between the cell and the aqueous environment.

D
The outward-facing orientation of hydrophilic heads allows interactions between the cell and the aqueous environment.

E
The outward-facing orientation of polar heads allows polar molecules to easily enter and exit the cell.
