Answer:
Many rare and/or endemic species exhibit one or more of the following attributes which make them especially prone to extinction: (1) narrow (and single) geographical range, (2) only one or a few populations, (3) small population size and little genetic variability, (4) over-exploitation by people
Biofilms are resistant to antimicrobial chemicals due to genetic diversity.
<h3>How do biofilms increase antibiotic resistance?</h3>
Biofilms are considered as a reservoir of genetic diversity. The emergence and spread of antibiotic resistance genes increase in biofilm due to horizontal gene transfer (HGT).
HGT can happen through the transfer of plasmids among microorganism cells in a biofilm through conjugation so that's why the antimicrobial resistance is higher in a biofilm than in free-floating bacterial cells.

In any scientific paper you can find th eprocedure part which should in detail explain how the procedure of a particular experiment was performed. Using these instructions we should be able to replicate an experiment, if the results that were obtained in the previoues experiments were correct of course.
