Answer:
Microtubules have shapes like a spindle and are arranged to form centrosome and a cluster of such microtubules form centriole.
Explanation:
Microtubules are seen in eukaryotic cells to give shape and structure to the cells and they form part of the cytoskeleton. They are known to grow long and are dynamic. Centrosomes are known to be main microtubule that are found in animal cells. They are organelles that are made from the arrangement of clusters of microtubules. The centrioles are organized microtubules that actually help to serve as skeletal system of the cell. These centrioles help to determine the locations of the nucleus.

Answer: Answer is below in the explanation.
Explanation:
As shown in the animation from my school, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes.

Answer:
The energy used for muscular cont ration is ATP(adenosine triphosphate) This is the energy currency produced in the mitochondrial during cellular respiration.
During muscles contraction.The ATPs is broken down to ADP and Pi.
This is the breakdown of energy rich bonds binding phosphate ions with ATP.The breakdown of the bonds produced -32kJper the 3 bonds in ATP. Therefore as each bond is broken, energy is produced for muscle contraction
It is an exergonic reaction with production of heat.
Thus ATP is used for muscle contraction.ADP is the intermediate of ATP when one Phosphate is removed during the breakdown.
Thus the sequence is Adenosine triphosphate (3 phosphate) to Adenosine diphosphate(2 phosphate) to Adenosine monophosphate (1 phosphate)
Each bond breakin gives equal energy of -32kJpermol.
