The space inside the nose. The nasal cavity lies above the bone that forms the roof of the mouth and curves down at the back to join the throat. It is divided into two sections called nasal passages. Air moves through these passages during breathing.
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).
The Gap 2(G2) stage of Interphase
Explanation:
In a eukaryotic cell, the cell cycle refers to both -cell growth and cell division - leading to the production of identical daughter cells. The cell cycle is basically divided into interphase (I) and mitosis (M).
The interphase, during which the cell grows and replicates its DNA takes place by the following stages – Gap 1 (G1), Synthesis (S), Gap 2(G2).
The cells grow and increase in size during the G1 period.
The G2 phase or the second gap phase the cell utilizes energy and produces necessary proteins for undergoing chromosome manipulation and other organelles and prepares the cell for mitotic cell division.
DNA replication mainly takes place in the Synthesis or the S stage of interphase with each of the chromosomes (46) is replicated.
Due to this DNA replication in the S stage, its content is doubled (4-N DNA content) when it enters the G2 stage and all the DNA is found within a single nucleus.
