You perform an experiment on two plants of the same species to find out what soil affects their growth the most. Both plants are

set outside in direct sunlight for 2 hours per day, and both receive 8 ounces of tap water each day in the morning. Plant A has regular dirt from your yard as its soil; Plant B has Miracle Grow Nutrient-enriched soil. You measure both plants each day at 8 AM with a ruler to determine how much they’ve grown.
Determine the control and independent and dependent factors of your experiment.

Answer:

Independent Variable - Soil, Dependent Variable - Height, Control Variable - Sun and Water

Explanation:

First we should define what the variables in the experiment are.

Independent variable is the aspect of the experiment that has a different value for each subject in order to find out how it affects the dependent variables.

Dependent variable is the variable that is kept under observation and recorded by the experimenters in order to track the changes and define its relationship with the other variables/parameters.

Control variable is the variable that is kept constant intentionally by the experimenters to be able to define the relationship between the other variables more clearly and easily.

In the example given in the question, there are one of each variable mentioned above which are, according to the definitions;

  • Independent Variable - The Soil
  • Dependent Variable - The Height Of The Plant
  • Control Variable - The Amount of Water and Sun Exposure

I hope this answer helps.

andrew-mc [135]
A general ballpark how one can predict the way how evolution will work in the future would be by thinking about the requirement of a certain area or environment and which changes would be necessary and relevant for any organism to thrive with its new changes. 

This could help people speeden up this process by enabling organisms to develop such traits faster, as well as ourselves.
