This is an example of facilitated diffusion.
Facilitated diffusion is the process of impulsive passive transport of molecules, it is the transfer of substances across a biological membrane from an area of higher concentration to lower concentration by means of carrier molecule.
The independent variable would be <u><em>a. concentrations of ethylene spray</em></u>

In virtually all scientific investigations that seeks to establish a cause-and-effect relationship, there are usually two main variables involved:
- <u>Independent Variable: </u>This is the variable that is manipulated by the researcher to cause or establish the extent of the effect it will have on the dependent variable that is being studied. It is the cause<em><u>.</u></em>
- <u>Dependent Variable:</u> This is variable that is measured by the researcher. It is the effect which is dependent on the independent variable.
In the scenario given, <em>different concentrations of ethylene spray</em>, is what the researcher manipulates, while <em>the length of ripening time, </em>is what is measured by the researcher.
The <em>the length of ripening time </em>is dependent on the <em>different concentrations of ethylene spray. </em>Therefore:
- the length of ripening time is the dependent variable
- the concentrations of ethylene spray is the independent variable.

Answer – DNA (Deoxyribonucleic acid)
The DNA provides the information for cell growth and function of all known living organisms. It also carries the information for their development and reproduction. Most of the DNA is located in the cell nucleus (in this case, called nuclear DNA), but some amount of DNA are also contained in the mitochondria (in this case, called mitochondrial DNA)
