What is the dependent variable in this experiment (Case Study 9)? [2 pt] the concentrations of the test substances used the test substances, butyric acid and tributyrin the Mitotic Index of the Caco-2 cells the cell type, Caco-2, used

The independent Variable in the given scenario IS "the concentrations of the test substances used"  

Explanation:

The independent variable characterizes as the variable that can be changed or controlled in a logical trial. It define the cause or effect behind a result. Independent variables are the factors that the experimenter changes to test their dependent variable. An adjustment in the Independent variables legitimately causes an adjustment in the dependent variable. The impact on the dependent variable is estimated and recorded.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
