Can someone answer this for me please show proof for brainliest and 5 stars here are the A. Model A would be the best model for the carbon cycle because carbon depletes over time as it is used by different organisms. B. Model B would be the best model for the carbon cycle because carbon will follow the same path when it is transferred from one place to another. C. Model C would be the best model for the carbon cycle because the carbon cycle has a definite beginning and end where carbon eventually cannot be reused. D. Model D would be the best model for the carbon cycle because the carbon cycle is a flow of matter which can take different paths bringing carbon back to the same place.

Dying 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.
