Mitosis is a four-stage process that creates two identical cells from one original cell. In Mitosis chromosome the cell divides intotwo identical sets daughter nuclei. in mitosis the mother cell divides into two daughter cells which are genetically identical toeach other and to the parent cell.Meiosis is a reduction cell division where the number of chromosomes is divided into half. In Meiosis it gametes formationsoccur in animal cell and meiosis is necessary for sexual reproduction. The meiosis has 6 phase: Meiosis I, Prophase I ,Metaphase<span>I, Anaphase I, Telophase I, Meiosis II</span>
1) Speed = distance / time
s = 60 / 2
s = 30 km/h
In short, Your Answer would be Option B
2) Speed = distance / time
s = 25/4
s = 6.25 km/h
In short, Your Answer would be Option B
[ Direction not needed as it is speed not velocity ]
Hope this helps!
