The Luria–Delbrück experiment () (also called the Fluctuation Test) demonstrates that in bacteria, genetic mutations arise in the absence of selection, rather than being a response to palmolive2day.comore, Darwin's theory of natural selection acting on random mutations applies to bacteria as well as to more complex organisms.
Max Delbrück and Salvador Luria won the Nobel Prize in. Demonstration. This demonstration shows the highly exothermic reaction between aluminium and iron(III) oxide that produces molten iron. This is a competition reaction, showing aluminium to be a more reactive metal than iron.
