Answer:
In prophase, the nucleolus disappears and chromosomes condense and become visible. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber.
Explanation:
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds betweenmonosaccharides. A dehydration synthesis reaction forms a bondbetween carbon atoms in twomonosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
<span>Multiple mutations in the DNA over several reproductions lead to mutations that give rise to malignancies. Cancer cells reproduce at an accelerated rate and do not die in the same time frame as normal cells, resulting in masses of cells (tumors).</span>
