- Fill in the Blank. Round it to the nearest whole number. A mutation occurs in a single bacterium that causes it to produce a new enzyme. This enzyme helps the bacterium process nutrients more efficiently, increasing the bacterium's odds of survival. Every 30 minutes, the bacteria in the colony divide, passing their genes on to their offspring. Some bacteria survive, while others do not. Because resources are limited, the colony has a steady population of 114 bacteria. The bacterial colony is shown below at three different time intervals. The picture would be here: Assume that the survival trend shown in the diagram continues. At 3.0 hours, the mutant bacteria will make up _____ percent of the entire colony.Give a reason why there’s a higher abundance of bacteria swabbed from the front of the compared ti the back of the hand.The iCHIP allows scientists to: grow bacteria in the natural environment. grow large numbers of a bacterial species and harvest large amounts of antibiotic. grow viruses effectively. grow a single diverse biofilm to later be tested in the lab.

Which type of realationship exist between the bacteria and the cows?Frederick Griffith documented bacterial transformation. Which statement is true concerning his experiments? DNA that was not contained within a live cell caused the death of the host organism. DNA from dead Streptococcus cells entered live cells and altered the live cell's characteristics. The two strains of Streptococcus were visually indistinguishable. Heat treatment of the Streptococcus strains destroyed the DNA molecules.Antibiotic resistance is a real concern for the continued existence of humans.
