Quaternary structures of proteins include different protein and non protein moiety to work together.
Option B
<h3><u>Explanation:</u></h3>
Proteins are the polymer of amino acids which are formed after several processing. The polypeptide chains are formed when the transcripted mRNAs are translated in the Ribosomes to produce the polypeptide chains. Then they are further processed by slicings and adding and cutting of several protein parts to this main polypeptide chains and they are slightly folded by means of hydrogen bonds between the polypeptide chain atoms to give a slightly coiled structure. Now this secondary polypeptide undergoes several structural modifications by chaperon proteins which introduce different ionic, disulphide, covalent etc bondings between different parts of polypeptide chain to produce a highly coiled tertiary structure.
Now in some proteins like haemoglobin, there are the protein part i.e globin associated with haem chains, which is the Quaternary structure of proteins. It's formed when different proteins are together associated to perform a particular function.
Both the symbiotic and the predator/prey relationships evolve together. For the symbiotic take the example of the bird on the rhino's back. They are both in the same environment so their relationship evolves (develops) together, helping each other out. The bird gets to eat the bugs on the rhino and the rhino is kept for being infested with bugs. In the predator/prey situation, think about the lion and antelope. The lion is the predator looking for food. The prey is what he eats. Only the fastest and most able-bodied lions are going to get the antelope. In order for the antelope to survive, it must become swifter and better able to conceal itself. The best of both animals will survive thus strengthening their blood lines. The difference between how the pairs evolve is their interaction. Symbiotic help each other; they don't do harm to one another. Predator/prey relationships is the opposite. The lion intends to do harm to the antelope. He needs the antelope for food.
