Answer:
Calvin cycle is the term which is used for the process by which the light reactions of photosynthesis produce energy in the form of Adenine tri phosphate (ATP).
Explanation:
Calvin cycle is an important phase of photosynthesis which consists of two stages. In the first stage, ATP and NADPH are produced from chemical energy in the presence of sunlight. In the second stage, water and carbondioxide combines with each other forming glucose 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 only.
Explanation:
Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose, the sugar in RNA is called simply ribose. The ‘deoxy’ prefix denotes that, whilst RNA has two hydroxyl (-OH) groups attached to its carbon backbone, DNA has only one, and has a lone hydrogen atom attached instead.
The main parts of a controlled experiment are the dependent variable and the independent variable...
