Answer:
In this, the controlled variables are stirring and type of sugar. As more stirring might elevate the amount of sugar that dissolves, and different kind of sugars might dissolve in distinct concentrations. So, in order to make sure a fair test, there is a need to keep these variables similar for each cup of water.
Explanation:
Answer:
<h2>Ethylene is a gaseous hormone in plants, it is a fruit ripening hormone.</h2>
Explanation:
Ethylene is a chemical signal through which ripening fruits trigger the ripening process in fruits, Studies on components of ethylene signaling have shown a linear transduction pathway leading to the activation of ethylene response factors. However, the whole pathway by which ethylene selects the ripening-related genes and interacts with other signaling pathways to regulate the ripening process still not yet fully known. Most fruits produce ethylene that starts the ripening process. Its level in under-ripe fruit is very low, but as fruit develop, the production of ethylene become larger that speed up the ripening process of fruit.
NaCl is dissolved in water so that in a given region or volume the concentration is initially higher in one part than the other l, thus simple diffusion will occur so that there is a net difference or 0, with respect to the concentration of NaCl in a particular volume of water than another. Basically the NaCl will be distributed throughout volume of water.
