The correct answer is: D.describes the 4 parts of the cell membrane that can move around

The fluid mosaic model is a concept used to describe the structure of the cell membrane. It suggests that the membrane is made up of a mosaic of different components, including phospholipids, proteins, cholesterol, and carbohydrates, all of which are fluid and can move laterally within the membrane. This movement allows the cell membrane to be flexible and dynamic, rather than rigid, which is important for processes like cell communication, transport, and the ability to change shape.

1.Phospholipids form a bilayer, with hydrophilic (water-loving) heads facing outward and hydrophobic (water-fearing) tails facing inward.
