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:
What disaster? I can explain it if there is a pic or something
Answer:
1. Óxidos são compostos binários formados pela reação do oxigênio com outros elementos.
2. Além disso, a tonificação também pode ficar feia e ocorrer em tons de preto e marrom. Nos casos mais graves, a tonalidade pode se transformar em corrosão e causar danos permanentes à superfície da moeda. Nos piores casos, a corrosão pode tornar a superfície da moeda porosa de tal forma que parece que foi tratada com jato de areia
3. (por exemplo, Li2O). Os óxidos são compostos binários de oxigênio com outro elemento, por exemplo, CO2, SO2, CaO, CO, ZnO, BaO2, H2O, etc. Estes são denominados como óxidos porque aqui, o oxigênio está em combinação com apenas um elemento.
