Provide reasoning with evidence based on the composition of biological macromolecules to support your claim.

Explanation:

Both the B cell membranes and the cancer cells are composed largely of phospholipids. Explain how the polar parts of the phospholipids from one cell interact with the phospholipids from the other cell when the membranes are fused, and how the nonpolar parts of one-cell phospholipids interact with the phospholipids from the other cell.

The polar parts of the phospholipids (hydrophilic head) from one cell to the other dissolve in water when the membranes are fused, and form hydrogen bonds with water. The non-polar portions of the phospholipids (hydrophobic tail) from one cell to the next to prevent water. They build a lipid bilayer between the hydrophilic heads where the hydrophobic tails are in between.

The heads are exposed to water when this layer is formed, while the tails only communicate with other tails, not the water.
