Makes ocean saltier, changes density an causes ocean currents
Answer:
Option D, is composed of a fluid bilayer of phospholipids with embedded amphipathic proteins
Explanation:
The fluid mosaic model is the depiction of plasma membrane whose main components are phospholipids, cholesterol, proteins, and carbohydrates.
The structure of plasma membrane consists of two layers of phospholipid molecules which are amphipathic or amphipathic (they possess both polar hydrophilic and non-polar hydrophobic ends).
Protein molecules also possess both polar and non-polar side chains. However, their poly hydrophilic linkages are towards the outer side and non-polar or hydrophobic linkage is towards the inner side.
Option D is correct
