The first period between the two monsoon, from March to early June, is the hottest and the most unpleasant of the year.
"At the end of anaphase, there is one cell with 20 chromosomes - 10 chromosomes at one end of the cell, and 10 chromosomes at the other end. Upon completion of telophase and cytokinesis, the single cell will be split into two cells. Each cell will contain 10 chromosomes, the same amount as the original progenitor cell."
