Which of the following describes a state of equilibrium? Select one:

a.
When the concentration of water outside a cell is the same as the concentration of water inside of a cell

b.
When a cell with a lot of water in it continues to absorb water

c.
When water molecules have stopped moving or vibrating

d.
When the roots of a tree absorbs nutrients from the soil

A

Explanation:

This is because on Equilibrium, the state of motion nor its internal state tends to change with time

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
