Pepsin is known as a digestive enzyme which is present in humans and other species digestive system. It is produced by the stomach, where it helps to digest the proteins and break down into amino acids which are present in food. In the stomach, a cell is known as a peptic or chief cell that helps to release Pepsinogen.

Then Pepsin hydrolyzed the proteins to polypeptide and starts protein digestion in the stomach.

4) If a dead organism is preserved as a fossil, which body tissues are most likely to survive? Why?
IrinaVladis [17]
The answer is hard tissue.

Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue (organs, skin, etc.). Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
