After 1 year of widely prescribed use, reports surface that bacterial infections disappear for up to 2 weeks after taking the prescribed antibiotic but then reappear, sometimes worse than the first time. Which of the following explanations might the FDA use to defend their choice of antibiotic to treat the infection? a) Patients' bodies are evolving over the year to create environments that are friendly to the growth of the bacteria. b) Patients are not taking the antibiotic for the length of time prescribed and so selection for resistant bacteria that can survive a limited course of antibiotic is occurring. c) Sexual dimorphism allowed for larger bacteria cells to outcompete smaller ones, therefore enabling larger bacteria cells to continue to multiply. d) Stabilizing selection over the year has allowed for the bacteria to remain at a high level in patients bodies.
