I think this layer formed by the strong currents or by waves slowly moving the shells to the shore along with other shells creating a layer of shells. If I’m wrong then I’m sorry:(

Answer:</h2><h2>when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell .</h2>
Explanation:
Cell membrane is composed of phospholipid bilayer . Cell membrane is hydrophilic at the surface of outside of the cell and inside surface of the cell thus both surface of cell membrane is a hydrophilic . Interiorly cell membrane is hydrophobic or nonpolar region because membrane composed of long fatty acid chain interiorly . Inner surface of cell membrane have no contact with water or polar molecules . When membrane binds to each other then the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell , while nonpolar parts of cell avoid water and create bilayer phospholipid where hydrophobic tails are in between the hydrophilic heads .
The two groups are Tyrannosaurus Ornithomimus and Tyrannosaurus Coelophysis which are different from one another in shape and body structure.
The word Ornithomimus means ''bird mimic,” because it resembles the bird i.e. they are toothless and had beaklike jaws while on the other hand, Coelophysis means 'hollow form' and the specie has hollow limb bones that makes Coelophysis is a lightly body dinosaur that make it a fast hunter.
