Why does the fracture plane usually pass through the center of cell membranes?
A)Fracture planes are naturally attracted to lipids.
B)Fracture planes take the path of least resistance through the block and the center of the membrane is such a path.
C)Fracture planes are repelled by the cytoplasm and pushed toward the membrane.
D)Fracture planes take the path of highest resistance through the block and the center of the membrane is such a path.
E)Fracture planes are attracted to phospholipids tails,especially their ends,by their hydrophobicity.

Question

Fracture planes typically take the path of least resistance through the block. Since the cell membrane is a lipid bilayer with hydrophilic heads and hydrophobic tails, the center of the membrane is a path of least resistance compared to passing through the hydrophilic heads or the cytoplasm. Therefore, the fracture plane usually passes through the center of cell membranes.
