Answer:
Based on the hypothesis, an increase in the ratio of Gi to Gs proteins coordinated signalling, would decrease cAMP concentration when GCPR binds to it, with the Gi function intact and able to oppose the Gs protein activation.
Evolutionary theory predicted that bacterial resistance would happen. Given time, heredity and variation, any living organisms including the bacteria will evolve when a selective pressure, in this case an antibiotic is introduced. However it also gives doctors an patient some specific strategies for delaying even more widespread evolution of antibiotic resistance; these strategies include; avoid mild doses of antibiotics over long time periods, don't use antibiotics to treat viral infections, when treating bacterial infection with antibiotics, take all the pills, and also using combination of drugs to treat a bacterial infection.
