Continental collision is a phenomenon of the plate tectonics of Earth that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountainsproduced, and two continents sutured together. Continental collision is known only to occur on Earth.
Continental collision is not an instantaneous event, but may take several tens of millions of years before the faulting and foldingcaused by collisions stops. The collision between India and Asia has been going on for about 50 million years already and shows no signs of abating. Collision between East and West Gondwana to form the East African Orogen took about 100 million years from beginning (610 Ma) to end (510 Ma). Collision between Gondwana and Laurasia to form Pangea occurred in a relatively brief interval, about 50 million years long.
Explanation: okay so cells have this mechanism to kill themselves if a bad mutation happens but when that breaks and the cell can longer do that it is considered a cancer cell the cell will continue to mutated and multiply if mutated enough it will be able to hide itself with regular cells, from the immune system after a long time it will get veins to give all the nutrition to the cancer cells making it grow more if lucky it will multiply and mutated but this mutations makes it think its a regular cell creating a cancer tumor
now cancer is beating cancer. eventually it will take over but you will have god cancer

Explanation: A protein called hemoglobin in the red blood cells then carries the oxygen around your body.
