Schools are in a unique position to promote healthy dietary behaviors and help ensure appropriate nutrition among America’s youth. Nutrition services should provide a variety of nutritious and appealing meals that meet the health and nutrition needs of all students. 

Questions 18-22 refer to the prompt below. To better understand the mechanism, researchers studied the effects of the azithromycin on the proteome of P. aeruginosa.  In order to do this they exposed multiple strains of P. aeruginosa to the azithromycin and compared the results to the same strains without antibiotic exposure. Below are results from a 2 dimensional gel electrophoresis. Figure 2.A: Example protein profile for P. aeruginosa. Proteins were labeled with CyDye and separated by 2-D gel electrophoresis on 24 cm pH 4-7 linear gradient strips followed by electrophoresis on 12% SDS-polyacrylamide gels.  Proteins were visualized by scanning for CyDye fluorescence.  The position of the identified protein spots that were modulated by azithromycin are indicated with circles and named.

Questions 11-14 refer to the prompt below. You are interested in better understanding dental caries so you study bacterial RNA levels in healthy plaques and dental caries.  Your results are shown below. Figure 1. Heat map indicating relative normalized RNA expression (log2 reads per million reads in each sample) of different enzyme-encoding genes or virulence genes by species in each patient. White indicates equal gene expression in eubiosis and dysbiosis, dark red indicates higher levels of gene expression in dysbiosis.
