Mitosis results in two diploid cells
meiosis results in four haploid cells

(a) Muscle B contracts and muscle A relaxes
(b) The Heart
Mitosis is the process describing the division of a cell into two genetically identical cells. It has 5 stages: interphase, prophase, metaphase, anaphase, telophase. During anaphase, the cell is elongated and the pair of chromosomes is drawn to the opposite sites of the cells, getting ready for the cell division that occurs at the next stage. Therefore, at anaphase the DNA is duplicated and the cells of the Tasmanian devil would have 28 chromosomes at this stage.
A: We say that it takes 500 to thousands of years to create an inch of topsoil. The reason is that soil is often derived from rock. The rock has to be broken into small pieces first. This happens by physical weathering: things like freezing and thawing in colder climates, and chemical weathering in warmer climates.
