==Key Stage 4==
===Meaning===
'''Antibiotic resistance''' is the tendency of [[bacteria]]l colonies to become immune to the use of [[antibiotic]]s.

===About Antibiotic Resistance===
: '''Antibiotic resistance''' is [[Scientific Evidence|evidence]] for [[Evolution by Natural Selection|evolution by natural selection]].
The process of '''antibiotic resistance''' of a colony of [[bacteria]] takes place over several generations.
#[[Antibiotic]]s are used to kill a colony of [[bacteria]].
#[[Bacteria]] within the colony are all slightly different due to genetic [[variation]] so a few may not be affected by the [[antibiotic]].
#Some [[bacteria]] survive the [[antibiotic]] due to a number of reasons, but a proportion of those is due to a [[variation]] that has made them '''resistant'''.
#In the next generation there will be many more resistant [[bacteria]] since the others have died and cannot [[reproduction|reproduce]].
#When [[antibiotic]]s are used again this removes all of the non-resistant [[bacteria]] leaving behind an entire colony of '''antibiotic resistant''' [[bacteria]].
: As a result of [[Evolution by Natural Selection|evolution]] many [[disease]] causing [[bacteria]] can no longer be treated with common [[antibiotic]]s.
