In the microdilution broth dilution method, the interpretive criteria for the susceptible, interme-diate, or resistant categories are based on the:
a. quantitative differences (i.e., CFU/mL) in the turbidity in the test well. b. correlation of the MIC with se-rum-achievable levels of the common doses of the antimicrobial agent and the-rapeutic outcomes based on clinical stu-dies. c. either the presence or absence of zones of inhibition. d. FDA's recommendations based on a na-tional database of participating health care agencies providing antibiograms for re-view and publication as a summative re-port.
In a mycorrhizal association, the fungus benefits mainly by ____

How are eukaryotic transcripts modified before they are used in protein synthesis?
What will be an ideal response?
How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of both energy intermediates in photosystems I and II?
A. Plants often increase the amount of NADP reductase, thereby increasing NADPH production to match ATP output. B. Increase the electrochemical gradient for H+ across the thylakoid membrane, producing more ATP but not NADPH. C. Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH. D. More pigment can be rapidly created for greater photosynthetic capacity, producing equal amounts of ATP and NADPH. E. Electron flow rate can be increased, increasing both ATP and NADPH production.
