What's the difference between protein and fixed oils

There are many differences! To start a fixed oil is a lipid (fat), which is a completely different type of macromolecule (***see attached pics***) than a protein. One of the most visible physical differences between the two is that fixed oils are non-polar molecules (hydrophobic="water-fearing"), meaning they will dissolve in water. Proteins are polar molecules (hydrophilic = "water-liking"), so they will dissolve in water.

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
