Which best explains why replicating an experiment should be done by someone other than the person who originally did the experiment? it shows that the results are the same using different methods. it shows that the experiment is easy to do. it shows that the results are as expected. it shows that the experiment is designed properly.

The correct answer is It shows that the experiment is designed properly.

Repeating the experiment by other scientists is important thing because that’s the way to approve the experiment design and result. Scientists repeat others' experiments to verify the accuracy of the findings (peer review)  and also  to refine the results or simplify the methodology.

The answer's d: it shows that the experiment is designed properly. Because when it's designed properly, anyone should be able to do it and get the same results.

cancer   is   essentially   uncontrolled   mitosis   of specialized cells

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
