Two proteins bind to the same ligand, and protein a has half of its binding sites occupied when the ligand concentration is 0.5 mm, while protein b has half of its binding sites occupied when the ligand concentration is at 0.3 mm. which protein binds the ligand more strongly, and what is the dissociation constant for that protein-ligand interaction? a) protein a binds more strongly, and k_d = 0.3 mm. b) protein a binds more strongly, and k_d = 0.5 mm. c) protein b binds more strongly, and k_d = 0.3 mm. d) protein b binds more strongly, and k_d = 0.5 mm. e) both proteins bind the ligand with the same affinity, and k_d = 0.4 mm.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
