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 dependent variable is the time needed to run the race, because it DEPENDS on the independent variable (the one not effected by another variable) so the dependent variable in this case would be time and independent would be distance

A. At what time of day does photosynthesis take place?
Ksenya-84 [330]

Answer:

Naturally: only during daylight hours

Artificially: all 24 hours (under perfect circumstances)

Explanation:

Photosynthesis can only occur when a plant receives energy from a light source. Naturally, the light source would be the sun which is only around for a certain amount of hours. If the plant is under an artificial light source, like a lamp, then photosynthesis can occur at all hours of the day.

Zolol [24]
Dispositional traits are personality traits that remain stable and relatively unchanging from about age. They refer to the tendency of an individual to behave in stable and predicted ways. It is similar with the concept of moods. Costa and McCrae believed that personality traits remain the same by the age of 30.

How is economics being used to solve environmental issues?
Andrej [43]

Explanation:

The environmental sciences have documented large and worrisome changes in earth systems, from climate change and loss of biodiversity, to changes in hydrological and nutrient cycles and depletion of natural resources. These global environmental changes have potentially large negative consequences for future human well-being, and raise questions about whether global civilization is on a sustainable path or is “consuming too much” by depleting vital natural capital (13). The increased scale of economic activity and the consequent increasing impacts on a finite Earth arises from both major demographic changes—including population growth, shifts in age structure, urbanization, and spatial redistributions through migration and rising per capita income and shifts in consumption patterns, such as increases in meat consumption with rising income (19, 20).
