A student noticed that when he charged a balloon, it was attracted to the wall. He tried to put another charged balloon on the wall close to the other balloon, but it would not stick. What is the best explanation as to why this happened? The charged balloon that was already on the wall did not attract the balloon, and it fell.
There were too few remaining positive charges in the room to transfer to the second balloon.
When the second balloon was placed close to the first balloon, the charge of that balloon repelled it.
When the second balloon was placed on the wall, it took on the charge of the wall.

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.
