An experiment has a high degree of internal validity when it shows convincingly that changes in behavior are a function of the independent variable and not the result of unknown variables.
<h3>What is internal validity and example?</h3>
Internal validity makes the conclusions of a causal relationship credible and trustworthy. Without high internal validity, an experiment cannot demonstrate a causal link between two variables. Research example You want to test the hypothesis that drinking a cup of coffee improves memory.
Controls are required to assure internal validity (causality) of research designs, and can be accomplished in four ways:
- (1) manipulation,
- (2) elimination,
- (3) inclusion,
- (4) statistical control,
- (5) randomization.

Answer: C) Solar
Explanation:
A non-renewable energy source is an energy source that can not be used again once it is already used. Water can be used again. For example, you can create electricity out of water, and the same water will work again to make more electricity. Geothermal heat will stay somewhere in the Earth, so it will come back and will be used again. Nuclear power can be used again when the weapon is launched, they can take the material and use it again for feature weapons. The answer has to be solar. Solar energy comes from the Sun, so it can only be used once.
