Answer: Hydroelectric power will be the best energy source.
Explanation:
<u>Solar energy-</u> It refers to the energy that is directly derived from the sun, and are later used to convert into some kind of electrical or thermal energy. For example, solar panels.
<u>Biomass energy-</u> It is a type of energy that are directly obtained from the plants as well as organisms. This can be regenerated again and again. For example, bio-gas and food crops.
<u>Hydroelectric power-</u> It is a type of energy that is collected, from the rapid motion of water. A dam is needed to construct across a narrow river, which will store water as a reservoir. And this water, when allowed to flow then it initiates the movement of the turbines and due to this continuous motion of the turbines, electricity is generated.
Thus, the most efficient energy source for the given area is the hydroelectric energy, that fulfills the condition for setting up dams in the two rivers, which will generate a huge amount of electricity.
Answer;
B. It arouses the body and expends energy.
Explanation;
-The autonomic nervous system controls the insides of the body: the viscera or gut. It carries information about the inside of the body to the CNS and controls the action of internal organs. The autonomic nervous system has two divisions: the sympathetic division and the parasympathetic division.
-The sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. The parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
