The heaviest elements settled in the Earth's center.
The Earth on the other hand starts with a core of iron and radioactive materials such as uranium and plutonium, which release energy in the form of heat, through a process known as nuclear fission. It went through a fusion stage - a "liquid-pasty" state - which allowed that, due to gravity, the denser materials sank towards the center, while the lighter ones floated towards the crust, a process called planetary differentiation.
Answer:
The correct answer is "p18, p21 and p27".
Explanation:
In this experiment, four proteins were blocked and the level of DNA replication was tested in different cell cultures to see which proteins may play a role in cell cycle. Based on the given data we can conclude that p16 is the only protein that appear to have a pivotal role in cell cycle, while p18, p21 and p27 apparently does not. We can conclude this by observing group 7 of cells, were cells have only p16 active and were able to have around 80% of DNA replication.
<span>What MUST occur before mitosis and meiosis can occur is B) DNA replication. DNA replication is a process of copying DNA into an identical copy. Before mitosis, the genetic material of the mother cell must duplicate so that each daughter cell have the same amount as the mother cell. On the other hand, meiosis is a reductive division. But meiosis II is similar to mitosis, so DNA replication is also necessary.</span>
