Why is it hard to kill bacteria?

Because they evolve like every other organism on the planet.





Pesticides are getting stronger every year because bugs are evolving from exposure to them, the ones with weak immunities are dying off leaving only the ones with stronger immunities to procreate. It's called Darwinism.





It happened in humans with more warlike cultures as well. The people who had a more peaceful culture in the past are on average smaller today then the ones who constantly went in medieval wars of physical strength or lived in the wild, like Africa. The same goes for cultures where survival was based on intelligence.

Reply:Because they're tough lil' bastards. They've been around for 3 billion years. They know all the tricks.
Reply:because they form endosperms that protect it from dying, to form the endosperm it inserts some of its genetic material into a protective coating





Endosperm is the albumen tissue produced in the seeds of most flowering plants around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This makes endosperm an important source of nutrition in human diet as well. For example, wheat endosperm is ground into flour for bread, while barley endosperm is the main source for beer production. Other examples for edible endosperm are coconut "meat", popcorn and banana.

Reply:well michael have you ever heard of lysol, idoit, it kills it real easy, or you just could hire a maid to clean your dirty *** house
Reply:It is usually just hard to kill all of them because there so many of them. They reproduce geometrically so it is often very hard to eliminate them.
