Answer:
Independent variable: ALTITUDE
dependent variable: GROWTH OF PLANTS
Confounding variable: STOREYS OF THE BUILDING
Explanation:
In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.
- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.
- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.
- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.
The warmer the star, the bluer it will appear. The cooler a star, the more red it will appear.
Proxima Centauri Red Dwarf Stars for example have significantly less heat, therefore their red color.
An engineering cycle is meant to assess the environmental impacts in relation to economic impacts on a product. The assessment is the whole life cycle of a product consisting of production, use phase and end of life. It's important because it helps mold the standard of living for generations to come and be sustained indefinitely. It protects against negative environmental factors but also reduces the cost of production for business', also.
