Explanation: Waxes are lipids, which are hydrophobic meaning they do not dissolve in water. Waxes, like other lipids are hydrocarbon chains. However, the monomer of waxes is fatty acid and alcohol. (usa testprep explanation)

a time line cause it goes from 685 to 978

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
