I have been stuck on these Biology Questions for 3 days! The questions are:
Give one difference between the phospholipids found in a cell-surface membrane and the phospholipids found in the skin's lipid layer (1 mark).
Explain how the arrangement of the phospholipids in the skin's lipid layer makes it more permeable than a normal phospholipid bilayer (2 marks).
Can some please explain this to me?
Or have I left it too late?
