what is antibiotic resistance
antibiotic resistance is when bacteria survive antibiotics due to mutations, meaning some bacteria are naturally more resistant than others
what is variation in bacteria
variation is the difference in bacteria caused by mutations, meaning some bacteria are naturally more resistant than others
what is selection
selection is when antibiotics kill susceptible bacteria, while resistant bacteria survive
what is inheritance
inheritance is when resistant bacteria pass their resistance traits to their offspring
what is gene transfer
gene transfer is when bacteria share gene, often through plasmids, spreading resistance between bacteria
why is this natural selection
because bacteria with beneficial mutations survive, reproduce, and become more common over time due to selection
what misconception should be corrected
bacteria do not try to become resistant. resistance comes from random mutations, not intention
how does this relate to human behavior
overusing antibiotics increases selection for resistant bacteria, making resistance more common
