Explanation:
Proto-oncogenes are genes that have the potential to turn normal cells to cancer cells if they mutate. Once they have a mutation, they are called oncogenes. These typically code for proteins that control the cell cycle and cell growth.
Ras proteins are intracellular, and act as molecular switches that can be inactive or active. If they are inactive and receive a signal from the extracellular space indicating that the cell has to grow, they bind GTP and become activated. Once active, they send further signals that stimulate cell proliferation and division. After a while of sending those signals, the Ras protein hydrolizes GTP to GDP because it has an intrinsic GTPase activity, and becomes inactive once again, stopping the growth signal.
Mutations in the Ras oncogene typically affect the GTPase activity, causing its loss of function and subsequently that the Ras protein stays permanently active. This, in turn, causes uncontrollable cell proliferation, characteristic of cancer.
<h3><u>Answer;</u></h3>
D) <em>The more dense oceanic plate subducts under the less dense continental plate. Subducted plate melts due to heat and friction. Melted plate, now magma, rises up to the surface.</em>
<h3><u>Explanation</u>;</h3>
- <em><u>Volcanoes may be formed at convergent plate boundaries or at divergent plate boundaries. </u></em>
- <em><u>When two tectonic plates collide, they form a convergent plate boundary. Normally, one of the converging plates that is the dense oceanic plate will move beneath the other, which is the less dense continental plate a process as subduction. </u></em>
- <em><u>The friction between the plates in the subduction zone as a result of constant movement, melts the Earth's crust causing the underneath rocks to turn into magma.</u></em>
- <em><u>The magma creates great pressure and rises towards the surface of the earth, and on reaching the surface it is called lava, and a volcano is formed.</u></em>
Answer:
Recently work in evolution theory has proposed that by relaxing selection pressure, which typically acts to streamline genomes, the complexity of an organism increases by a process called constructive neutral evolution.
