WebFinal answer. Step 1/3. When conducting an antibiotic sensitivity test, it's important to test the bacteria during the log phase of growth rather than the stationary phase. This is because during the log phase, the bacteria are actively dividing and have a higher metabolic rate, making them more susceptible to the effects of antibiotics. how much is the naturalization fee https://amadeus-templeton.com
