Developed from the 1950s through the 1970s, plate tectonics is the modern version of continental drift, a theory first proposed by scientist Alfred Wegener in 1912. Wegener didn't have an explanation for how continents could move around the planet, but researchers do now. Plate tectonics is the unifying theory of geology, said Nicholas van der Elst, a seismologist at Columbia University's Lamont-Doherty Earth Observatory in Palisades, New York.
What is cyanide poisoning? Cyanide poisoning is a condition that develops when you inhale, touch, or swallow cyanide. Cyanide is a poisonous chemical gas that prevents your body from absorbing oxygen. The lack of oxygen can damage your organs and be life-threatening. Factories that make plastics, paper, jewelry, or textiles.
 Carbon monoxide binds to the hemoglobin, cutting â¦ off the oxygen  supply. Cyanide poisoning requires cyanide ions, and these ions  mess with an important enzyme in the mitochondria of the cell,  called cytochrome c oxidase.In this way, carbon monoxide prevents  the oxygen from getting to the cells, while cyanide prevents the  cells from generating the energy.he electron transport chain allows a great concentration of protons (H+ ions) to build up in the matrix of mitochondria so that they can diffuse back through a channel which in turn synthesises ATP. So basically cyanide stops the last step of cell respiration from occurring and as such inhibits ATP synthesis.
