Answer:
This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.
*Independent variable: DIFFERENT SOILS
*Dependent variable: Porosity
Explanation:
- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.
- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.
