<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>
A substance that releases hydroxyl ions in water is a base. Acids on the other hand release hydrogen ions when dissolved in water, while salts release sodium. To define acids and bases the Arrhenius definition is used by scientists---this describes what substances are produce by each type of solutions. Under the Arrhenius definition salt and water can be used to predict the result of the neutralization of an acid with a base.
In Chemistry, Bronsted-Lowry definition has superseded the Arrehenius definition.
The plasma membrane and cell wall are two different structures. The cell wall is the outermost structure of plant cells, providing rigidity. The plasma membrane lies just inside the cell wall.
The correct answer would be A. The agent of metamorphism that would cause for the overall composition of a rock to change would be hydrothermal solutions. These solutions contain mineral substances that are dissolved in the hot water. When in contact with a rock, the minerals may change the composition of the rock.
