Answer:

An independent variable is the one which can be changed in an experimental setup and the effect of the change can be observed on the changes of dependent variable. A dependent variable depends on independent variable. The dependent variable in this case is the growth of mold on the bread. The independent variable is the type of bread and moisture content.The effect of change of independent variable can be observed on the growth of molds which is a dependent variable. The researcher should use a quantitative approach to accurately measure the dependent variable.

How are the hardy-weinberg principles used in the analysis of codis genotypes and other strp-locus comparisons?
lana66690 [7]
<span>HWE is used with COIDS and non CODIS eligible DNA profiles to provide statistical caluclations for the rarity or uniqueness of profiles. Each STR kit test for a certian number of loci. Each lous has a set ladder of observed alleles. Each of these alleles has value for its observed frequency in a population. It is the rarity of each allele at each location that will give you the value for rarity of the profile as a whole. This rarity fo the profile is calucalted in CODIS under certian circumstances using to determine the eligibilty of a partial profile or a forensic mixture to determine its eligiblity for the different leves of the database.</span>
