Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange

Explanation:
Generally, hurricane causes transfer of heat from the ocean to the atmosphere through evaporation. The evaporation of water from the sea surface into the atmosphere is enhanced by hurricane's surface wind, which transport the water vapours to the part of the atmosphere called troposhpere. The wind speed in an hurricane is directly related to the surface pressure of a storm, the stronger the difference in the air pressure in the ocean surface, the higher the wind speed.
