Meiosis. Chromosome abnormalities usually happen as a result of an error in cell division. Meiosis is the name used to describe the cell division that the egg and sperm undergo when they are developing. Normally, meiosis causes a halving of chromosome material, so that each parent gives 23 chromosomes to a pregnancy.
Somatic cells or body cells have a dipliod or full set of chromosomes. Gametes or sex cells, also called germ cells, have a hapliod number of chromosomes or half the number. Somatic cells are diploid cells, whereas the gametes are haploid cells. Meiosis does not take place during the production of somatic cells, whereas meiosis takes place during gametogenesis (production of gametes) giving rise to haploid cells. Somatic cells do not fuse during sexual reproduction, whereas gametes fuse during sexual reproduction giving rise to a diploid zygote.Somatic cells are found almost everywhere in the body, whereas gametes are restricted to certain parts
Covalent bond is when two atoms share one or more pairs of electrons, an example of this could be H20 or C02.
ionic bonds are when one or more electrons from am atom are removed and attached to another, which can result in positive or negative ions which attract each other, an example of this could be table salt.
In aplastic anemia, then lab result will be decreased in all blood component( white blood cells, red blood cells, and thrombocyte).
Aplastic anemia is caused by the bone marrow failure. Bone marrow is the place that produces blood cells, so the decrease wouldn't be in the red blood cell only, but in other blood cells too. There shouldn't be any iron deficiency or decreases in the mean corpuscular volume
