Researchers are designing several experiments to test the ability of Salmonella bacteria to develop antibiotic resistance. A culture of Salmonella bacteria is exposed to the same concentrations (200 mg/L) of an antibiotic for four days. The table shows the number of isolated resistant bacteria over a four-day period. Which of the following statements best explains these results?
A - The bacteria were not affected by the antibiotic.
B - After being exposed to the antibiotic, the bacteria altered their DNA.
C - A new species of bacteria emerged after the antibiotics were introduced.
D - Random mutations led some bacteria to be resistant and, over time, they increased in the population.

The blue circle is a plasmid that contains genes that confer resistance to specific antiobiotics. d. The blue circle represents a double-stranded molecule of DNA.arrow_forwardIn Hershey-Chase experiment, bacteriophages protein coats were tagged with radioactive isotope S-32. These phages were used to infect E. coli cells and the cells were further centrifuged to form pellets. Why was the radioactivity level of S-32 found greater outside the cells compared to the E. coli cell pellets? Explain briefly.
