exposure to drugs causes mutations which produce drug-resistant populations of microbes.
<h3>What is the effect of using same type of drug?</h3>
Drug-resistant populations of microbes arise when the exposure to drugs causes mutations because this exposure produce resistance which leads to mutation in the organism. Due to this mutation, the drugs did not work on the organism anymore.
So we can conclude that exposure to drugs causes mutations which produce drug-resistant populations of microbes.
