Refer to Animation: Fluid Mosaic Model. Although the phospholipid molecules can be in constant lateral movement, they very rarely flip from one side of the bilayer to the other. Which of the answer choices could explain this? a. The head groups are too large to fit between the interior fatty acid tails. b. The cholesterol keeps the phospholipids on the correct side. c. The molecular attraction between the fatty acid tails is too strong. d. The head groups are repelled by the hydrophobic membrane interior.

. d.The head groups are repelled by the hydrophobic membrane interior.

Explanation:

The fluid mosaic model explains structural components biological membranes (plasma membrane).

The keywords in the model are fluid, mosaic and model.

The fluid - shows that it components are always moving, not solid

Mosaic - collection of things stuck together

Model - representation of real life

The definition of the model is fully described from the keywords in the terms above. Phosopholipids, cholesterol and proteins form a mosaic (pattern) within the cell membrane.
