The biological membrane is a fluid structure in which phospholipids and proteins move freely between sides of the membrane. It consist of two layers of phospholipids, the structure is held together by the phospholipids hydrophobic tail interactions. The two layers of phospholipids and proteins either crossing the layers or on the surface of the layers. Please reword the question as the options appear to be missing... ;-)
