For determination of \( E \). coli cell growth, scientist applied the serial dilution method and plant the cells into agar plate in triplicates. After one day incubation, the numbers of colonies were Plate I: \( 520-915-1150 \) Plate II: \( 96-225-150 \) Plate III: \( 15-24-9 \) a) What are the problems and expectations about these values? Why the scientist faced with these problems? (3 pts) b) Please write the dilution factors of tubes and plates. \( (3 \mathrm{pts}) \) c) Please calculate the cell number in original culture with using the proper value. ( \( 6 \mathrm{pts}) \)
