The similarities between an onion and whitefish cell are in the process of mitosis. Mitosis has 4 stages and they all occur the same in plant cells ans animal cells. The 4 stages are prophase, metaphase, anaphase and telophase. In prophase condensation of chromosomes occurs while in metaphase the chromosomes move to the center of the cell and line up. In anaphase the chromosomes separate and finally two new nuclei begin to form in the telophase
<span>The similarities between an onion and whitefish cells exist in the cell division process. Normally the basic process of mitosis cell division is similar for plant cells and animal cells, but there are fundamental differences that mark the mitosis of plant and animal cells. Basic similarities of onion cell and that of whitefish embryo cell is that in the four phase of mitosis namely, Prophase, Metaphase, Anaphase and Telophase occurs in similar way. In Prophase for both cells the chromatin condensed and in metaphase the chromatin aligns in the center of cell and kinetochores of chromosomes attached with the microtubules of spindle from opposite poles. In Anaphase stage, the chromatids from the metaphase plate are separated and shifted to opposite poles.. Finally at Telophase, the cell divides via cytokinesis. The fundamental difference between Onion cells and Whitefish cells can be found in the process of cytokinesis. </span>
Yes you can. The atomic mass measured from the proteins and neutrons in an atom, since you know he number of protons, you can subtract and be left with the number of neutrons.
