A lack of genetic variability in the species :)
A lack of genetic variability in the species #2
The most important single factor necessary for creating diversity of life is genetic variability. This variability allows for the adaptation of species to different environments, leading to the evolution of diverse life forms.
It is a diversification of traits within a species. An example of this is ladybugs with different numbers of spots.
If you have an example of a common biological apparatus you are probably holding a beaker. The beaker is the most common and well recognized biological apparatus.
what is the purpose, strenghts, weaknesses and provide an example for biological?
A major factor affecting the standard error of the mean (SEM) is the sample size. As the sample size increases, the SEM decreases because a larger sample provides a more accurate estimate of the population mean, leading to less variability. Additionally, the variability of the data itself, measured by the standard deviation, also influences the SEM; higher variability results in a larger standard error.

Technical replicates: measure quantity from 1 source. This measures the reproducibility of the results. The differences are based only on technical issues in the measurement. (I weigh myself three times, do I get different weights? How different?) Biological replicates: measure a quantity from difference sources under the same conditions. Tumors from 5 different people with lung cancer may show similar gene expression patterns. These replicates are useful to show what is similar in your replicates and how they are different from a different set of conditions (ie. treated, normal).
