1 - characteristics that remain in the common ancestor and the modern organism
2 - characteristics that are new and have been modified from what was found in the common ancestor
1 - characteristics that are new in the common ancestor and the modern organism
2 - characteristics that have been modified from what was found in the common ancestor
1 - characteristics that have been modified in the common ancestor but not in the modern organism
2 - characteristics that are new in both the common ancestor and the modern organism
1 - characteristics that remain in the common ancestor and the modern organism
2 - characteristics that are new in both the common ancestor and the modern organism

A= 1 - characteristics that remain in the common ancestor and the modern organism

2 - characteristics that are new and have been modified from what was found in the common ancestor. Help it helps :)

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
