Answer:
Independent variable - vitamin gro and exercise routine.
Dependent variable - growth of children or nieces.
Explanation:
There are two variables present in an experiment called dependent and independent variables.
Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.
In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.
