Ernest Rutherford’s experiment supported that the atom contains a positively-charged nucleus. Why then does our data show that the electrons are not all crashing into the nucleus? Choose the best answer. Group of answer choices A. Electrons are also positively charged and like charges repel one another.

B. Electrons must all have the same spin and this cannot be accomplished if they are all located in the nucleus.

C. Electrons only exist in their excited states but if a ground state were possible, then they would be located in the nucleus.

D. Electrons only exist in certain energy levels both in the ground state and excited state.

E. All of the above explain why the electrons are not all crashing into the nucleus.

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.
