Answer:
The process is energetically favourable.
Explanation:
Formation of lipid bilayer is energetically favourable.
Energetically favorable means no energy input needed for reaction to take place. That means it's spontaneous.

QUESTION 8 When phospholipids are mixed with water, they spontaneously form lipid bilayers. Why is this energetically favorable A. None of these answers are correct B. Hydrogen bonds form between neighboring polar head groups of phospholipids, drawing them together. C. Van der Waals interactions between the hydrocarbon chains are stronger than hydrogen bonding interactions. D. Water molecules would otherwise form cage-like structures around the hydrocarbon chains, decreasing entropy. E. All of these answers are correct

Incorrect Question 2 0/1 pts How are lipid bilayers formed? What is their fluidity dependent on? Hydrophobic interactions are the driving force of forming bimolecular sheets of lipids spontaneously. Due to the hydrophobic effect, any tears in the lipid bilayer cause it to spontaneously rearrange to eliminate the free edge. Membrane fluidity depends on the percentage of unsaturated fatty acids Hydrophobic interactions are the driving force of forming bimolecular sheets of lipids spontaneously. Due to the hydrophobic effect, any tears...
