RAS is a very important protein that belongs to a class of protein referred to as GTPases and plays a crucial role in switching on pathways that control cell growth, proliferation, apoptosis and differentiation and migration. For RAS to become inactive it must hydrolyze GTP to GDP which slows down the process of cell proliferation. Mutation in one copies of RAS will result to cancer because the mutated copy will permanently attach to GTP and remain in activated form which will lead to uncontrollable cell division and hence development of cancer.
The Moon is thought to have come from the Earth. In 1975, the giant impact hypothesis was put forward. This suggests that the Earth was hit by a planet about the size of Mars around the time of the formation of the solar system approximately 4.5 billion years ago, and the impact caused part of the outer layer of the Earth to spin off and form what is now the Moon.
D is probably right cos you are comparing data
