To obtain identical copies of a single cell scientist make a

To obtain more amount of single cell, a method called cell culture is employed.

Cell culture, otherwise called limited cells, will be cells that are legitimately arranged from a life form's tissues. Whenever placed under the correct conditions essential cells will develop and multiply, however they are just ready to do so a limited number of times. As far as possible is identified with the telomere length toward the finish of the cell's DNA.

As cells experience every cell division, a little portion of the telomere is lost after each time DNA is copied. This procedure in the long run prompts a phase of senescence, where the cells can never again separate. Persistent cell lines, then again, can get away from the ordinary limitations of the cell cycle and develop inconclusively, making them incredibly helpful for long haul inquires about.  

i do not know and i have a 100 in this class

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
