Outer layer of skin consist of keratin which is also found in hair. Callus is the accumulation of dead cells result due to friction and pressure exerts on the part in which they are present.

Answer:
Due to no transfer of resistance allele.
Explanation:
The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance
The coast is warmer and better environment
