What would happen if you take antibiotics? you will get betteryou will get another viral infection Correct Response nothing you will get worse Question 20 5 / 5 points Which is a plausible effect of taking oral antibiotics? Correct Response the antibiotics could unintentionally kill good bacteria living in your intestines, leaving you more susceptible to infection by pathogenic bacteria the antibiotics could harm your own body cells. the antibiotics could interfere with your body’s own ability to produce antibiotics, and actually end up prolonging the infection. the antibiotics could destroy viruses that have infected your body
