Doctors need to be careful not to
give their patients an antibiotic
such as penicillin too often. If
the same antibiotic is prescribed
too many times, it can become
less effective against bacteria.
Explain why this is so.

Bacteria becomes resistant to antibiotics
over time. The is because each time
antibiotics are used, some bacteria
survive.
They survive due to variation in the
bacterial population. Some bacteria have
genes that make them resistant to the
antibiotic (caused by mutations).
The surviving bacteria then reproduce
and create offspring that are also
resistant. Over many generations, the
whole population is resistant.
