which of the following statements must be true about the data sets a and b displayed in the histograms above?

1 answer:

5 0

Based on the dispersion of the data in the attached diagram, we can say that a. The standard deviation of data set A is greater than the standard deviation of data set B.

Standard deviation:

Is used to check how far apart the data in a set are
Is calculated by square rooting the variance

When the standard deviation is high, it means that the data in a set are spread apart which is the case with dataset A as we can see that the frequencies are 8, 2, 1, 2, and 8. The 8s and the 2s are quite far apart so the standard deviation here is significant.

In the case of dataset B, the standard deviation is not as much as most of the frequencies are close to each other - 1, 2, 8, 2, 1.

In conclusion, dataset B has a lower standard deviation than dataset A.

Describe two reasons why geneticists have reevaluated their traditional view that one gene codes for one polypeptide

Nadya [2.5K]

For a long period of time, geneticists believed that one gene codes for one polypeptide. This hypothesis has been re-evaluated for two reasons. Firstly, some genes do not encode polypeptides, but functional RNA molecules. Secondly, due to the phenomenon of alternative splicing, some genes can encode several similar but not identical polypeptides. This phenomenon is present only in eukaryotes and it is based the fact that different parts of some genes can be used during gene expression.
