All the molecules in the bilayer are in a low energy state, so are stable on a molecular level. The layer is kept stable because the phosphate head is attracted to the water while the lipid is repelled. This lines up the molecules. They have no reason to move. In a bilayer, the molecules are back to back, so lipids are trapped in a hydrophobic section.
It is a Phospholipid Bilayer. Each phospholipid is composed of a hydrophilic head and 2 hydrophobic tails. The tails are lipids which are 'water fearing'. So the structure naturally forms with the Heads to the outsides and tails to the insides; forming a double layer structure (ie. bi-layered).
The polar tails face away from the watery environment while the polar heads face the watery environment.
what separates prokaryotic and eukaryotic cells from the watery environment in which they exists
I believe you are referring to phospholipids. They form a bilayer around the plasma membrane of the cell to keep the cellular contents in and selectively allow things to come in and out of the cell.
yes it can as its outside edges stick out of the phospholipid bilayer exposing it to the watery environment (polar/hydrophilic) and part of the protein is inside the bilayer along with the phospholipid tails (hydrophobic/nonpolar).

The negativley charged phosphate head of the molecule is hyrophyllic (it is attracted to water). The tail is hyrophobic (repelled by water). In an effort to keep the phosphates in contact with water and the tails away, the molecules form a bi-lipid layer.
