The fluid mosaic model explains: Select one: a. why active transport occurs across a cell membrane. b. the arrangement of cell membrane components. c. the movement of sodium ions across the cell membrane. d. why fluids collect in a cell under hypotonic conditions

The fluid mosaic model explains the arrangement of cell membrane components. It states that the membrane components are constantly moving. The phospholipid bilayer compromises hydrophobic fatty acid tails and hydrophilic phosphate heads, this hydrophilic/phobic nature determines the unique structure of membranes.
