genetics, evolution, and natural selection can be the cause of variations.
Meiosis is responsible for genetic variation
Statistical dispersion, a quantifiable variation of measurements of differing members of a population
DNA and RNA are molecules responsible for heredity and variation in organisms. They carry genetic information that is passed down from one generation to the next, and mutations in these molecules can lead to variations within a species.
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.
Precision refers to the level of consistency or exactness in measurements or data. It is a measure of how close repeated measurements or values are to each other. A high level of precision indicates a small range of variation, while low precision indicates a larger range of variation.
The process responsible for genetic variation is genetic recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. Mutations, which are changes in the DNA sequence, also contribute to genetic variation.
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.
Lateral Runout and Thickness Variation. I have this question on today's class too, I found it.
The precision of measurements affects the precision of scientific calculations by influencing the accuracy of the final result. More precise measurements lead to more accurate calculations as there is less uncertainty or variation in the data used for analysis. In contrast, less precise measurements can introduce errors and inaccuracies into the calculations.
When temperature increase the volume also increase; but if you think to volumetric titrations the effect is without importance.
