Using the following statements, draw a rooted phylogenetic tree with the seven walrus genera that are italicized below: Dusignathinae and Odobeninae are sister clades. Dusignathinae contains Gomphotaria and Dusignathus. Odobeninae is comprised of Aivukus and Protodobenus, as well as a clade called Odobenini. Aivukus is the earliest diverging genus in Odobeninae and Protodobenus is sister to Odobenini. Within Odobenini, Valenictus and Odobenus are sister taxa, and they form a clade that is sister to Ontocetus.

Dependent variable are those variables that changes with the change in variables that affects it.

Explanation:

Dependent variable responds or gets affected to change. They are not constant. It can be possible that dependent variable is relying on independent variable as independent variable does not change with change of any of the factor in an experiment.  

Sometimes, mentioning not the units leads to insufficient data of the variables. A constant is something whose value cannot be changed and is used for comparison purpose. According to the question, Rose is constant, height is dependent variable , different types of soil are independent variable.
