For comparison, its worth noting that high intensity interval training (HIIT) on a hydraulic resistance system can burn a whopping 10.315 calories per minute (10). A genetic bottleneck reduces the genetic variation in a population. Bacteria acquire antibiotic resistance through gene flow; the antibiotic-resistance gene then increases in a population as the bacteria survive and reproduce.
