<span>C. Experimental group </span><span> Basically the experiment has to be done with proper reasoning to make the scientific explanation satisfactory for all concerned. Scientific method is a process that is ongoing. Based on the observations via properly done experiments, a scientist can come to a proper conclusion. Although the procedures followed during experiment may vary, but the final result should always be the same. </span>
A controlled experiment is a scientific test in which a single variable can be directly manipulated to know the effect of manipulation over the variable under study. A control variable is used over which no manipulation is performed. It is kept as a benchmark for comparison of observations by using the control and experiment group in an experiment.
An experiment group is a set of independent variables over which the tests are performed in a controlled experiment.
We can say that the water is the solvent, and the powder is the solute. This is also a solution altogether.
<span>Explanation:- A solute is the thing being dissolved into the solvent. While the solvent is what when the solute is being dissolved in. Together, they make a solution. </span>
My guess would be an energy source, water, and an atmosphere.
Explanation:
Whatever lives there is going to need energy and water to survive. The atmospheric layer will protect the planet like ours protects Earth. Hope this helps! :)
