Answer:
The independent variables are the level of tiredness and the number of hours slept by the volunteers.
Explanation:
Independent variables are those that act on the dependent variables influencing a result, which can be observed by the researcher. In summary, the independent variable is one that can influence. In the case of the question above, we can see that the number of hours slept by the volunteers influenced the level of tiredness of the volunteers. These two variables were able to influence the level of proactivity and performance of the volunteers in their activities, which allows us to determine that these two variables are the independent variables of the study.

<u>Answer:
</u>
A reaction in which the reactants have more energy than the products is always an Endothermic reaction.
<u>Explanation:</u>
The word "exothermic" means "turning out".In endothemic reaction, less amount of energy is sufficient to break the bonds that exist between the reactants when compared to the amount of energy that is formed when new bonds are created.
The chemical energy that is stored within a product is nothing but its potential energy that can later be released. An example of an endothermic reaction is the burning of wood. when you burn wood, you can see that it releases energy in the form of heat and this warms up the surrounding environment.
The correct answer would be, generate her own conclusions and recommendations.
While others argue that the batteries still do not hold enough charge and remain cost prohibitive for products like those of her company. To demonstrate her own original thinking, Hermina should generate her own conclusions and recommendations
Explanation:
When you are at a point where you have to take decision about something after analyzing different options, then the best way to take decision is to do what you think will be beneficial for you and the concerned people around you.
So when Hermina reads several reports about what options to choose to convert her company's products to solar energy, she should rely on her own conclusions. Hermina should generate her own results and recommendations.
