Plz ! asap! i will make you the brainliest! a student conducted an experiment that used two rose plants to determine if a liquid formula for fertilizer was better than a dry formula. he tested each fertilizer on a single plant for one month, and he concluded that the liquid formula was better. when he described his conclusion to his teacher, she told him he needed to conduct additional trials. the teacher most likely asked for additional trials because
a. she did not believe the new formula plants grow better than the old formula.
b. it was necessary to see data from more plants before the conclusion could be accepted.
c. it was necessary to have tested the fertilizer on different kinds of plants.
d. she thought he should test additional fertilizer formulas on the same two plants.

it was necessary to see data from more plants before the conclusion could be accepted

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

answer; i believe that the correct answer is (lung);
