I think it’s 3 but it very well could be 4 to this is kinda tricky
Answer:
Chromosomes will be seen in the nucleus of dividing cells (during mitotic and meiotic cell divisions) because they are visible when a cell is dividing as oppose to non dividing cells. Also, all processes of cell division from prophase, metaphase, anaphase to telophase will be seen :)
Embryonic stem cells have the ability to become all types of cells.
That means that those stem cells can become kidney cells, lung cells etc.
If you nurture these stem cells with healty cells from a tissue or an organ, those stem cells will eventually grow into and become the same as the cells you nurtured the with.
This means that you could use embryonic stem cells to create healthy kidneys, skin and other types of tissues/organs.
Answer:
Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!
Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.
Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.
The right answers are:
create two identical cells ==> mitosis
create four non-identical cells ==> meiosis
create haploid cells ==> meiosis
creates diploid cells ==> mitosis
occurs in all cels other tha gametes ==> mitosis
occurs in all cells related to sexual reproduction ==> meiosis

Explanation:
Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments.
Bioremediation is used to clean up oil spills or contaminated groundwater.22 Jun 2020
