Final answer:

In this activity, the variable that will be changed is vessel radius.

Step-by-step explanation:

In this activity, the variable that will be changed is vessel radius. The radius of a blood vessel can be changed rapidly by vasoconstriction and vasodilation, which dramatically impacts resistance and flow. Small changes in the radius will greatly affect flow since it is raised to the fourth power in the equation.
