plz look phto and help (louis pasteur)

Louis Pasteur was one of the many people who started an area of science called microbiology. He's mainly known for his work with milk. Pasteur noticed milk that is about two days old starts to develop bacteria. This makes it dangerous drink, and people could catch diseases if they continue to drink it. This process is called, "pasteurisation".

normally working animals are domesticated and ruled by a master, a domesticator (tamer), to perform basic and important functions on a farm, for example. the value used in this context is animal labor in exchange for food. it is not so much a contrast to the story told by napoleon and the pigs, since the animals of that particular farm also performed functions on the farm through domestication. the only thing is that in this case, who rules them is a pig, also an animal, but very respected, to whom the other animals lent him submission. that's about a strong relationship of dependency between animal and owner.
