Monoclonal antibody (MW = 155,000 kg-moles/m3) is being purified from hybridoma cell culture supernatant by ammonium sulfate precipitation. The antibody concentration in the starting material is 0.5 g/1 and 30% of the antibody could be precipitated using 1 M ammonium sulfate cut. What salt concentration would have resulted in 90% precipitation of the monoclonal antibody? The solubility of the antibody in salt free water is 390 g/1.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
