Starfish do not appear to have bilateral symmetry and yet the diagram indicates they are bilaterians. What other characteristics do they have that would confirm that
classification?
O a water vascular system and tube feet
O external digestion and the ability to regenerate portions of its body
O an internal skeleton and a complete digestive system
O a bilateral larva and an anus that forms from the first opening in the embryo

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
