Single line text.You place 1 ml of a bacterial broth culture into bottle A containing 99 ml of sterile water and mix. You take 1 ml from bottle A and transfer it to bottle B, which contains 99 ml of sterile water. What is the dilution of the bacterial culture in bottle B?Describe how you would make 10 ml of a 1:500 dilution of bacteria by performing TWO SEPARATE DILUTIONS in series? Consider the accuracy of the pipetting so that you don’t make a single dilution that is too large.
