Identify the dependent variable on the growth of tortoise shell graph

Length of the shell (mm)

Explanation:

An independent variable is the one which can be controlled or changed in an experiment to test it's effect on the dependent variable. The dependent variable can be define as the variable which can be tested or measured in an experiment.

Here, in the given graph the length of shell(mm) is the dependent variable which depends upon the age in years. As with the age of the tortoise the length of the shell will also increase.

this would be a math

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
