Im not sure but if you think of it, the one that you didn't put any salt is a independent variable because it doesn't really rely on anything it doesn't have salt. The Dependent variable would be the 2nd and the 3rd cup because it doesn't have much salt but the 4th cup has lots of salt so its basically controlled. Hope it helps !

I believe the correct answer would be metabolism. This comprises all of the reactions inside organisms that allows them to sustain life. There are two categories of such namely, anabolism and catabolism. Hope this answers the question.
<span>Catabolism is all of the chemical reactions that break down molecules, either to extract energy or to produce simple molecules for constructing others. Anabolism refers to all of the metabolic reactions that build or assemble more complex molecules from simpler ones.</span>
As far as I know, only the 3rd step, from all the mentioned above occur during meiosis I.
Hope it helped,
Happy homework/ study/ exam!
