Oncogenes result from turning on, or activating proto oncogenes. Proto oncogenes are genes that code for positive cell cycle regulators, so proto oncogenes code for proteins that turn on cell division. Proto oncogenes are normal genes, but when they are mutated, they become oncogenes. Oncogenes are expressed too much, which makes them turn on cell division too much, which is cancer.
C would be the correct answer because The glacial budget refers to the balance between the amount of inputs versus outputs affecting the glacial system. So the glacier loses mass as evaporation will increase due to warmer temperatures and there will be melting at the snout. This part of a glacier is known as the zone of ablation.
