Describe two reasons why multiple sets of research on the same or related information is
important.

When a research is conducted and results are deduced, scientists tend to perform the experiments again and again to check if the results are similar each time. These multiple set of research again and again is important to check and prove that our results are authentic.

Sometimes, it might happen that there might be some other external factor due to which the results are occurring as seen. Re-checking of the results s important so that it might be made sure that no external factor is the reason of the shown results.  

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

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
