They want to determine if the samples contain a toxin or a virus. Material from each sample is used to inoculate leaves on the plant type where the lesions were observed. Both sample 1 and sample 2 produce a lesion. Material from that lesion was then taken and applied to a second set of leaves using either undiluted, or various dilutions of the prepared sample as indicated below for the two different samples. Choose one of the answers below and briefly explain why you choose that answer. A. Both samples contain viruses but they are different viruses. B. Both samples contain toxins but they are different toxins. C. Samples 1 contains a toxin and samples 2 contains a virus. D. Sample 1 contains a virus and sample 2 contains a toxin. No dilution 1/10 1/100 1/1000 Sample 1 Sample 2

Five different strains of E. coli (1, 2, 3, 4 and 5) were streaked onto a series of tester plates. After incubating the streaked plates for an appropriate amount of time, they were scored for growth (+) or no growth (-) of the various strains on each respective plate. MM denotes minimal medium, CM denotes complete medium and letters A, B and C denote the supplements added to minimal medium. Assume supplements A, B and C construct the complete bjochemical pathway. The results are shown below. Tester Plate Strain MM MM+ A MM + B MM+C CM 1 +. +1 +. +. 2. +. 4 Which supplement is most likely the end product? Select one: O a. B cross out O b. C cross out O c. A cross out +. 3.

Based on the fingerprint, do you think Son and Father were independently infected by L. monocytogenes from two different sources, or from the same source? Explain your answer in simplest terms

What is the microbiology laboratory test that Identifies Pseudomonas maumuensis and what are the results of the tests that identify it? please include your sources in MLA. examples are hemolytic tests, lipid concentrations, genomic tests etc.

can you please help me to write short answer for these question 1.why it is important to complete morphological and cultural characterizations before pursing physiological testing? 2.In regard to taxonomic classifaction of bacteria, what is the relationship between physiological and genetic differentiation of bacteria?

Which of the following is the best description of the process shown in the image below?

What is this image and the parts labelled in it?

Following is the data and notice that it is a terrible idea to culture hMSCs longer than 10 days. You’re strongly Days # cells0 50001 75002 125003 125004 218005 287006 530007 1143008 1653009 19200010 19200011 11680012 8950013 8830014 78300 Part1 You are working for a start-up that is pursuing a clinical trial. The trial involves grafting hMSCs intopatients suffering from interveterbral disc disease using a degradable polymer scaffold. You are going to 3Dprint a porous cylindrical scaffold that is 2 cm in radius and 1 cm in height (matching the dimensions of adegenerated disc). Assume a porosity of 50%. You will fill available volume of the scaffold with hMSCs at adensity of 1 million cells per cm3. Based on the data above, what starting number of cells will you use andhow long will it take you to get enough cells for the trial? Part2The trial is a failure (patients did not report any reduction in back pain). Your team wants to try againusing 85% hMSCs and 15% nucleus pulposus cells .…

You have 1 ml of kombucha. You remove 0.1 ml of this and mix it with 9.9 ml of fresh tea. You mix the second tube, then remove 1 ml of this mixture and add it to 9 ml of fresh tea. You then mix this, and remove 0.1 ml of this solution, and plate it. The next day, you return to find 362 colonies. What was the concentration of the cells in the original mix? Show your calculations.  My professor worked this problem out in class but she used a different method than that from the Khan academy videos on youtube and I am getting lost in the steps. Do you mind labeling?
