Sometimes, bacteria are like kids who play hide and seek. When we use antibiotics to find them, most of them get caught, but some sneak away and come back stronger next time. That's how they learn to resist antibiotics.
Bacteria can copy themselves, and sometimes they make tiny mistakes when they copy. These mistakes might help them survive the antibiotic. Then those strong bacteria grow more and more, so the whole group becomes harder to catch next time.
Examples
- A child who hides better than the others gets to play again next time.
- A group of ants that find a new food source become stronger over generations.
- Some students who cheat on a test pass it and teach their friends how to cheat too.
