This means that the dose of amoxicillin needed to prevent S. aureus growth in a culture medium A. should be less than 2 mg/ml B.should be at least 2 mg/ml C. needs to be determined by an antibiogram D. is unknown as not enough information is providedPhenol Red Test Question: what would be the outcome of innoculating fresh cultures of Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis inside the phenol red broth after incubation?Question:- what conditions do bacteria need to grow ? think about the condition needed for yeast and if these conditions are similar.
- Question:- Rust fungi (biotrophs) and leaf spot fungi (necrotrophs) can both cause foliar infections. You are running a controlled experiment with bean plants; in one treatment you inoculate with rust and in another you inoculate with leaf spot pathogens. Your treatments result in identical disease incidence (50%) in both treatments. After 6 weeks further growth, which treatment do you predict will result in the greatest reduction in plant growth compared to the control? Compare and contrast the physiology of these two diseases to support your prediction.All questions a) Name structures P, Q and R. b) Name substance S . c) What is the enzyme encoded by gene I.
