The independent variable would be <u><em>a. concentrations of ethylene spray</em></u>
<u><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:
Option C, functional theory
Explanation:
As per the functional theory , the attitude of an individual depends on his/her needs or goals. In other words it can be said that attitude of a person depicts the hidden motives of their lives. Attitude is one of the basic need of an individual which shapes their life desires and expectation and also is an imperative part of the cognitive system.

Answer:
Explanation:
Inside the cell, there is a greater concentration of water molecules and outside the cell, there is a lesser conc. of water molecules. So, through osmosis, the water will move to a solution of higher solvent concentration.

You may heard of the term mutation. Even during cloning, which is done by the process of DNA replication. Certain agents referred to as mutagens bring about changes in the chromosomal constitution, or how certain genes are arranged on the chromosome. Some physical factors include X rays and gamma rays, while some chemical factors include EMS and nitrogenous gases.
