    behavior as measured in the two-choice assay a) 3rd instar larvae: From previous studies of our lab (Newquist, Novenschi et al. 2016) we learnt that each larval ORN is functionally diverse and each ORN differentially contributes to olfactory behavior in the Drosophila melanogaster larvae. Based on these results, we postulated that individual ORNs might be differentially modulated under starved state conditions. To begin to address this question we started with a panel of seven different

    A. Melting Point and percent yield of Dimethyl Fumarate Dimethyl Fumarate was not successfully created during the course of this particular experiment, likely because of a failure of the bromine to mix with the other components of the test tubes.
