The dependent variable is what changes because of the independent variable, while the independent variable is what is purposefully changed by the experimenter, since it is the variable that is being tested.
So, in this problem, you are purposefully changing the distance of the race to see whether or not the amount of time taken to complete the race will change because of the varying distances.
This means that purposefully changing the distance of the race is the independent variable that is being tested and that the amount of time that the runner takes to complete the race is the dependent variable because it changes due to the independent variable.
Sorry for being so wordy.
In short,
Independent variable- the one that's being tested and that is purposefully changed.
Dependent variable- the one that changes because of the independent variable.
Hope this helps.

The complementary strand it what matches to the original. T means the complementary letter will be A (and vise versa), C means the complementary letter will be G (and vise versa).

<span>The main reason surface area to volume ratio is important to a cell is because the surface area to volume ratio determines the rate at which cells uptake nutrients, liquids or gases. For instance, I have two organisms, A and B. Organism A has a surface area to volume ratio of 6:1, whereas organism B has a surface area to volume ratio of 3:1. As organism A has a greater surface area to volume ratio, it means that organism A will be able to take up nutrients, liquids or gases via diffusion or osmosis at a greater rate than organism B, as it has more surface with which to exchange nutrients, liquids or gases. </span>
The nutrients get to the cells in a flatworms solid acoelomate body by diffusion process. Flatworms feed primarily on protozoa and bacteria, smaller worms and tiny organisms, dead or alive, that they come across. Based on the species of the flatworms , they also consume plant materials. They rely on diffusion to transport oxygen and nutrients to their internal tissues.
