1) Bacteria evolve resistance antibiotics by
a. A completely different process than that which results in insects evolving insecticide
resistance
b. Learning to avoid the antibiotics
c. Some bacteria, by chance, having a mutation that enables them to survive and pass on
the genes for immunity
d. Being in tissues that arenโt reached by the drugs

a. Evolution
b. Natural selection
c. That all organisms produce more offspring than can survive
d. That natural selection is non-random
4) A multicellular organism
