Answer: The cell membrane represents several types of different molecules.
Explanation:
Its basic function is to separate the intracellular part from the extracellular parts. Biological membranes are globally built on the same principle and consist of lipids, proteins, glycolipids, and glycoproteins. Two layers of lipids form the structural matrix of the membrane. Membrane proteins are key to membrane function. The composition also includes sugars that do not come independently but are covalently bound to membrane proteins or lipids.
I have no clue of "which of the following" because i cannot see the answers but,
The Great Migration, or the relocation of more than 6 million African Americans from the rural South to the cities of the North, Midwest and West from 1916 to 1970, had a huge impact on urban life in the United States.
