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.

Absorbing CO2 into the blood is a part of the respiratory system!
The amino acids<span> in a protein are bonded to </span>each other<span> with peptide bonds - hence the term for a polymer of </span>amino acids<span> is a polypeptide. There are 20 </span>different amino acids<span>, and they all share the same general </span>structure<span>. In the centre of the </span>amino acid<span>is an assymetric carbon atom called the alpha carbon. I hope that you have a good day and i hope this helps you out
