Studying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this.

a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers?

the work is not scientific because the data are not processed in one location.
the work is not scientific because the simulations are not reproducible.
the researchers applied creativity to solve a problem in running an experiment.
the researchers used only well-established scientific techniques.

I believe that the best answer to the question: Which statement best describes the work of these researchers, would be: The researchers applied creativity to solve a problem in running an experiment.

Explanation:

Scientific experimentation, and testing, can be a pretty difficult thing to do, especially when it comes to certain biological and molecular topics. The unwinding of proteins to discover how they have been folded, and thus understand how this process can originate certain diseases, is very complicated and it would be impossible to carry out in a study. However, if researchers had given in to the difficulties, and immensity of the obstacles, to carry out their experimentation, instead of finding solutions that were scientifically acceptable, and also efficient, then we would have never known this key aspect of molecular biology, that could solve a lot of conditions that are untreatable today. These Stanford researchers did exactly that, use ingenuity, within the scope of what science allows, to pursue their goal by making use of the resources that they did have available, and which permitted the study to be carried out. This is why the answer is the third option.

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

because of
