They're super small! Some can multiply and mutate in minutes! And they're EVERYWHERE! Meet the Microbes
Microbes are the oldest form of life on Earth. Some types have existed for billions of years. These single-cell organisms are invisible to the eye, but they can be seen with microscopes. Microbes live in the water you drink, the food you eat, and the air you breathe. Right now, billions of microbes are swimming in your belly and crawling on your skin! Don't worry, over 95% of microbes are harmless. Three major types of microbes are BACTERIA,VIRUSES, and PROTOZOA.

These computer viruses can take over a computer's files similar to the way that microbe viruses take over healthy cells. Picture of a sick computer
