Biological Processes in Nature

As an example of biological process I will talk about frying an egg. Since every biological process is a chemical reaction which results in transformation this would be a great example. In its natural state an egg has yellow middle part called yolk and clear, white substance around the yolk called albumen. Both of these parts are composed of protein. As soon as an egg is placed on a frying pan and temperature becomes more than the protein can withstand, albumen of an egg becomes solid white and yolk becomes hard, and of a different consistency. This process is called denaturation, and once denaturation of protein happens it is irreversible. This example is an example of biological process since once substance was transformed to another.
