John wants to test how temperature affects the mass of sugar that can be dissolved in water. which of the following factors will john manipulate in the experimental group? a. the mass of the sugar b. the volume of the water c. the temperature of the water d. the time of day

The answer you're looking for is C. The temperature of the water. I hope that you found this answer helpful!

C. The temperature of the water.

Explanation:

In an experimental setup, an independent variable is the one which can be manipulated so as to know it's impact over the dependent variable. The dependent variable is the outcome of the experiment.

In the given example, the temperature of the water is the independent variable which can be changed or manipulated in the experiment manually so as to know it's impact over the dissolution of sugars in water.

trachea, alveoli, lung capillaries, arteries

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
