Question
Mitosis is the process by which a cell replicates its
chromosomes and then segregates them, producing two identical nuclei in preparation for cell division. Mitosis takes place inSolution
In animals, mitotic cell division is only seen in the diploid somatic cells. However, there are few exceptions to this where haploid cells divide by mitosis, for example, male honey bees. Against this, the plants can show mitotic divisions in both haploid and diploid cells.
- The speed of a boat in still water is 9 km/hr, and the current’s speed is 2 km/hr. The boat takes a total of 14 hours to cover ‘x’ km both upstream a...
A boat can cover 220 km in downstream in 11 hours and 126 km in upstream in 18 hours. Find the speed of boat in still water
A man can row at 4 kmph in still water. If the velocity of current is 2 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
What is the speed of boat in still water?
