- Given this research scenarios kindly construct a research framework. A researcher is interested to test the antibacterial activity of a Philippine Plant crude extracts against Beta-lactamase producing Klebsiella pneumonia isolated in a hospital setting. He will use the following concentrations of crude extract, 500mg/ml, 250mg/ml and 100mg/ml. Positive control: Tetracycline 10mg/ml and DMSO as the negative control.1. You are studying a biochemical pathway and isolate Neurospora mutants I, II, and III. Mutant I can grow if you supplement the medium with Z. Mutant Il can grow if you supplement the medium with X, Y, or Z. Mutant III can grow if you supplement the medium with X and Z, but not with Y. Draw a biochemical pathway that shows the correct order for compounds X, Y, and Z and for the enzymes that each mutant is defective for.5. The data in the table below were collected during a laboratory session assaying for thekinetics of Acid Phosphatase.
