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.

Analysis of the pathological constituents GIVE THE FOLLOWING: - Name of Test/Test Reagent - Positive Result 1) Protein (Note: Presence of protein in urine is termed as proteinuria or albuminuria) A. Heat and Acetic acid test Fill a test about ¾ full of urine. Heat the upper portion gently to boiling for 1 -2 minutes being careful not to shake the tube. Rotate the tube to prevent overheating. A turbidity may be due to albumin, phosphates or carbonates. Add 3 drops of acetic acid drop by drop while boiling between each drop. If turbidity disappears, it is due to carbonates and phosphates. B. Heller’s nitric acid test Place 1 ml of urine sample in a test tube. Hold the test tube in an inclined position and carefully pour 1 drops of conc HNO3 down the side of the test tube. Note formation of white ring at the zone of contact of the two solutions which is an indication of the presence of protein.
