Explanation:

Cell undergo cell division (mitosis or meiosis) as part of healthy development of a living organism. Before division, the cell during the resting phase( Interphase) makes two copies of all its organelles including nucleus, as it would form two daughter cells (in mitosis) or four daughter cells (in meiosis)

Arturiano [62]

Granite is a type of intrusive igneous rock

Explanation:

An igneous rock formed from hot magma or lava cools, solidifies or crystallizes to form rocks.

Based on the rate of cooling of magma, igneous rocks can either be intrusive or extrusive.  

A slow cooling of the magma deep within the earth without reaching the surface of the volcano leads to the production of intrusive igneous rocks.

This slow cooling leads to crystallization forming large crystals visible to the eyes with a phaneritic texture.

Granite has the best phaneritic texture among intrusive igneous rocks. Granite crystals can be easily visualized and are constituted by minerals like white feldspar, black hornblende, translucent quartz, and platy black biotite.

Extrusive igneous rocks like basalt are formed from microscopic crystals from fast cooling of magma.

The chromosomes are separated by a structure called the mitotic spindle.

A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation.

Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
