Final answer:
A complicated and scientific term for 'fart' is 'flatulence,' which refers to the mixture of gases produced by bacteria in the process of gut fermentation.
Step-by-step explanation:
A complicated word for a fart, which is the outcome of gut fermentation processes by bacteria in our digestive system, is flatulence. This biological process involves bacteria breaking down the undigested remnants of food, resulting in the production of various gases.
These microorganisms share a commonality with those used in beer brewing, where the fermentation process also involves the conversion of sugars into alcohol and carbon dioxide. The gas produced during gut fermentation that leads to flatulence mostly consists of nitrogen, hydrogen, carbon dioxide, methane, and sometimes a small percentage of oxygen.
