Providing long-term control over the body's internal conditions
Keeping conditions within a normal range
Adjusting the "set point" for body temperature based upon level of activity
Answer:
The correct answer will be option-E.
Explanation:
The nervous system is one of the most important systems of the animal body which helps in the transmission of the signals to and fro from the body to the nervous system.
The evolution of this system is the basis of the evolution of the human species as it helped and tried the species to sense the external environment most efficiently as well as improved the response to the environment.
The nervous system improved the response by forming new interactions with each other and responding to it by reducing the response time through reflex actions which formed fast acting response to the environment. The transmission of signals improved as the cells were long-lasting that is present form the birth of an organism
Thus, option-E is the correct answer.
To form ammonia, we can react 2 molecules of N₂ with 6 molecules of H₂. Once the reaction has completed, the total molecules of each gas will be: 1 molecule of nitrogen, 3 molecules of hydrogen, and 4 molecules of ammonia.
<h3>How to predict the total molecules of reactants and products?</h3>
The formation reaction of ammonia needs one molecule of nitrogen and 3 molecules of hydrogen. The reaction is as shown in the equation below:
N2(g) + 3H2(g) --> 2NH3(g)
2N2(g) + 6H2(g) --> 4NH3(g)
They will form a new product as four molecules of NH₃. Speaking in the present time after the reaction has completed, half of the reactants (N₂ and 3H₂) are gone to form the ammonia. Hence, the correct answer is: 1 N₂, 3 H₂, and 4 NH₃.
This question seems incomplete. The complete query is as follows:
"We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, NH₃. How many molecules of each type of gas will be present once the reaction has completed?"
