Description of the structure of the cell membrane.

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.

radioactive dating, also known as  radioisotope dating  is a process that in  estimating the approximate  age  of  rocks. these data can be analyzed from  the studies dealing with the  decay of the radioactive elements that are present in these rocks. in nature, there are a few types of materials or atoms which are quite unstable and they spontaneously decay or breakdown to form other kinds of atoms.
