What type of transport was shown here? -passive diffusion
-because the molecules moved DOWN the concentration gradient.

-active facilitated diffusion
-because the molecules moved DOWN the concentration gradient with the help of proteins.

-passive diffusion
- because molecules moved UP the concentration gradient.

- active transport
-because the molecules moved UP the concentration gradient with the help of proteins.

- active transport

- because the molecules moved UP the concentration gradient with the help of proteins.

Explanation:

In simple diffusion, small noncharged molecules or lipid-soluble molecules pass between the phospholipids to enter or leave the cell, moving from areas of high concentration to areas of low concentration (they move down their concentration gradient).

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
