When platelets attach to collagen threads in an injured vessel the platelets swell, form extensions and then stick together. as a result of these steps what structure is formed?

Before the plug forms,  a platelet will stick to the blood vessel (adhesion), change its shape and signal other platelets to come help (activation and secretion). Then they stick to each other (aggregation).

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
