#SCPH01 Biochemistry
  1. Each and every individual bacterium, in order to survive, develops a resistance to the antibiotic when exposed to it, and passes that resistance on to future generations.
  2. Only some bacteria, in order to survive, develop a resistance to the antibiotic when exposed to it, and pass that resistance on to future generations.
  3. A few bacteria have a natural heritable resistance to the antibiotic, so they survive when exposed to it, and pass that resistance on to future generations.
  4. All the bacteria have a natural heritable resistance to the antibiotic, so they survive when exposed to it, and pass that resistance on to future generations
