I put snails and Elodea plants into test tube bottles that contains Bromothymol Blue. The left four were put under dark light and the right four were put under bright light. Explain what each of the test tubes went through (photosynthesis, cellular respiration, both, or neither) Test tube 2 has a snail. Test tube 3 has a elodea plant. And test tube number 4 has both of them. All of them were a green color (medium level of carbon dioxide) at the beginning.

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

the correct answer in apex is tissue development, i know because i just had this question
