Explain the basis for the great diversity of proteins in living organism.

Explanation:

Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
