Bacteria knows what they’re doing.
It’s almost as if somewhere in their genetic makeup, they have a sinister brain plotting to destroy the likes of your bodily functions. I learned today in my Biology class that, if a certain bacterium has a attribute like a flagellum or other things that might help it move around or attach to objects, it can grab on to a bacterium that doesn’t have these characteristics. After the new bacterium is produced from the other one, it now has all the attributes of the one that grabbed on. It’s almost as they help each other out in the attack on your body.
