    Dr. Brown conducted three distinctive experiments in order to understand how an individual’s immunological phenotype is the result of its genotype‚ the environment‚ and development. For the first experiment‚ Dr. Brown’s research was testing how selection on basal and maximal metabolic rates affect immune function. In addition‚ Dr. Brown had four hypotheses for this particular experiment‚ two were for basal metabolic rate and two were for maximal metabolic rate. Moreover‚ trade-off with BMR decreases

The physically cohesive biofilm is the strongest biofilm of them all‚ and the one produced by the WspR genotype. It presents a very strong biofilm with very good growth and attachment‚ that when poured out onto a petri dish retains its structure as a single flexible piece. Physically cohesive biofilms also show evidence of cellulose along with other EPS substances

Natural selection acts on the phenotype‚ or the observable characteristics of an organism‚ such that individuals with favorable phenotypes are more likely to survive and reproduce than those with less favorable phenotypes. If these phenotypes have a genetic basis‚ then the genotype associated with the favorable phenotype will increase in frequency in the next generation. Over time‚ this process can result in adaptations that
