Over long periods of time, layer upon layer of sediments form, putting intense pressure on the oldest layers. Under great pressure and heat, lower layers of sediments eventually turn into rocks. Common examples of sedimentary rocks include sandstone, limestone, and shale.

What is the relationship between chromosomes spindle fibers and centromeres
Lerok [7]
SPINDLE FIBERS

In Mitosis, Spindle Fibres form at opposite poles of the cell and meet at the equator. Collectively, they form a spindle-shaped structure which attach to Centromeres.

CENTROSOMES

The organelle located near the nucleus in the cytoplasm,
composed of 2 centrioles that divides during S Phase

Centrioles are surrounded by a mass of proteins (Pericentriolar Material (PCM))

Migrates to opposite poles of the cell during mitosis

Involved in the creation of spindle fibres

CHROMOSOMES

A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

Centromeres
The constricted region joining the two sister chromatids that make up an X-shaped chromosome. It also serves as the point of attachment for spindle fibers when the spindle fibers are pulling the chromosomes toward the centrioles (situated on opposite poles in a cell) prior to cytokinesis.

Which organelle<br> produces the cells energy
Zinaida [17]

Here is a Answer to your question:

Mitochondria

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
