genetics, evolution, and natural selection can be the cause of variations.
Mitosis is the part of the non sexual cells. These cells do not help reproduce anything with variation. When these cells replicate the replicate in the exact same way, remaining unchanged. this is the reason mitosis limits genetic variation.
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
Meiosis is responsible for genetic variation
Statistical dispersion, a quantifiable variation of measurements of differing members of a population
Prophase 1 (APEX)
The measurements for all members of the sample are the same.
Engineering measurement tolerances are the permissible limits of variation in measurements. Example a piece of steel 25mm square where it would be allowed to be +.001mm or -.001mm on this size. The plus or minus is the tolerance
A large degree of variation between individual measurements, in terms of the units used.
Continuous variation is variation without fixed values such as height or shoe size. Discontinuous variation has fixed values/catagories such as eye colour or hair colour. Hope this helps!
Lateral Runout and Thickness Variation. I have this question on today's class too, I found it.
When temperature increase the volume also increase; but if you think to volumetric titrations the effect is without importance.
