please help with whatever possible. thank you so much in

Name One use of serial dilutions is to calculate the concentration of microorganisms. Since it would usually be challenging or even impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count (usually between 25 to 250 colonies is the goal). Since each colony on an agar plate theoretically grew from a single microorganism,...

1. You are studying phage transduction and trying to deliver a kanamycin resistance gene from one strain of bacteria to another using phage. The kanR gene is FAR away from the lambda prophage in your bacterium. Choose which type of transduction should you use for your experiment and explain why. a. lambda phage, specialized transduction b. lambda phage, conjugation C. T4 phage, generalized transduction d. A different phage with mitomycin C induction 2. A pig is infected with two subtypes...
