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
