1. Elemental hydrogen produces Balmer lines at 410 nm, 434 nm, 486 nm, and 656 nm. Which of the following would most accurately describe the absorption spectrum for hydrogen? a. Like all light, this will generate a continuous spectrum when reflected through a prism. b. Hydrogen will absorb energy at twice the emission wavelength, leaving empty sections of the spectrum at 820 nm, 868 nm, 972 nm, and 1312 nm. c. Due to the quantization of energy, the absorption spectrum for hydrogen will result in the production of only four lines, at 410 nm, 434 nm, 486 nm, and 656 nm. d. Hydrogen will absorb energy at half the emission wavelength, leaving empty sections of the spectrum at 205 nm, 217 nm, 243 nm, and 328 nm. e. Hydrogen will absorb energy at the same energy that it emits energy, leaving empty sections of the spectrum at 410 nm, 434 nm, 486 nm, and 656 nm.

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.
