The variable that is intentionally manipulated or changed in a controlled experiment is know as the B) Independent Variable.
This is done, as the question states, to test the hypothesis. In other words, it is changed in order to see what results are produced, then the results are analyzed, and ideally an explanation of the changing results will arise and progress can be made in the experiment.
Condensation because the water droplets are being formed by the water vapor in your breath against the cold window makinng condensation due to the drastic temperature difference between your breath and the window
In the absence of competition, P. aurelia grew better than P. caudatum. Every daythere were more P. aurelia than<span>P. caudatum</span>
Explanation:
1. A decrease in the number of greenhouse gases that humans produce will result in lowered global temperatures. This will allow the ice sheets in the polar regions to increase increasing also albedo.
2. Using light-colored building materials on houses and pavement in urban centers will work towards increasing albedo as more sunlight is refelcted back by built environments.
3. Decreased deforestation/increase in aforestation increases the earth’s sirface albedo because vegetation reflects back more sunlight than the earth’s bare surface.
