Explanation:
Blood is actually 55% plasma and 45% solids (blood cells).
Chromatin: is a complex made up of genetic material (DNA), wrapped in protein , such as histones,present in the cells of eukaryotes<span>.
</span>Chromatids :before the cell divides, the chromosomes are copied, and each chromosome consists of two segments in the form of bat, the chromatids. Each cromátide corresponds to a copy of one of the 46 strands of DNA in every one of my cells (sperm and eggs).
Chromosomes: are present in cells that are in the process of Division. In place of chromatin, we can observe in the nucleus, small bat-shapedbodies quite stained, easily visible when observed under a microscope<span>.</span>
hope this helps!
