Oh I love this question. "MRSA" or "Mithicillin resistant staphylococcus aeues" is bacterial infection.
MRSA is unique to bacteria for it's ability to replicate and maintain homeostasis even when an antibiotic in introduces to destroy it. This resistance can have dangerous consequences usually mainly due to the requirement of needing aggressive in hospital treatment, its tendency to spread fast, and its ability to hit you so hard you could go into Sepsis. Its additionally dangerous because it's prevalent in the hospital.
While many people like to blame doctores for, "over prescribing" of antibiotics the fault doesn't't rest with a provider. In regards to evolution when a person is sick with a a common staphy infection people are prescribed antibiotic. The patient is required and usually specifically told to take the full course. The reason why is because the bacteria that would cause MRSA would still not have developed but are still alive following a treatment... However they gain the ability to become antibiotic resistant if the full course of antibiotics are not followed to a "T".
Drinking salt water is harmful because it messes up the salt concentration in each of your red blood cells. It over loads the salt in it and causes the cell to swell up and burst due to it trying to let in more water to balance the salt concentration out.
One way by which wetland controls flood is by absorbing water from rivers. Wetland absorbs water and and store it. Afterwards it releases slowly.It behaves like a sponge. It also protects nearby houses flooding and vegetation too.It reduces the water flow and settles down the sediments and pollutants also.
