Hi I hope you're doing fine. I need help with these questions please!   thank you!

DIFFERENTIAL TESTS/CHO METABOLISM 6. You streak out E. coli and B. subtilis each onto a starch plate. You incubate the plates overnight, and the following day you flood the plate with iodine and you obtain the results shown below: Е. coli B. subtilis Describe what you see on the plates. What can you tell about B. subtilis and E. coli based on these results? (4)

Helping tags: Biology, bacterial count, dilution, serial dilution WILL UPVOTE, just pls help me answer the following questions and explain them clearly. Pls show complete solutions also for the computation part. Thank you. 1. A bacterial culture was grown for 9 hours. At 3-hour interval, the culture was sampled to determine the population of the culture, by transferring 25 ml of the suspension to 225 ml 0.85% NaCl. Three consecutive dilutions were further made by using 1 ml aliquot in 9 ml of 0.85% NaCI. One ml from each dilution was plated in each of duplicate plates. The following table shows the results of the plating method. Sampling COUNTS 2nd dilution 3rd dilution 4th dilution 0,0 30: 35 250;245 1st dilution 1st 2nd 3rd 0; 0 240; 235 TNTC 55; 60 5; 6 TNTC TNCT TNTC TNTC a) Illustrate the dilution series used and label the final dilution of each dilution. b) Determine the bacterial count (CFU/ml) every 3 hours of incubation for 9 hours. Show all computations.
