Answer:
She can conclude that the reaction started with three nitrogen atoms because she can be based in the law of conservation of matter which states that the amount of matter in a system is conserved: there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.
Explanation:
In science, a law is a general statement that explains a large number of observations. One law that provides the foundation for understanding in chemistry is the law of conservation of matter: it states that in any given system that is closed to the transfer of matter (in and out), the amount of matter in the system stays constant, or in other words, the amount of matter in a system is conserved.
So, in this case, for Marcia to conclude that the reaction started with three nitrogen atoms, she can be based in the law of conservation of matter, and because the matter of that system is conserved, there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.

<h3><u>Answer;</u></h3>
Nodes of Ranvier
<h3><u>Explanation;</u></h3>
- Nodes of Ranvier are the spaces between the myelin coating on the neuron's axon.
- Nodes of Ranvier have space exposed to conduct electricity with the environment to propagate the signal down the axon.
- At the nodes of Ranvier, electricity can be conducted within the cell's environment, and the electrical signal will be propagated down the axon.
Cellular Respiration is the process performed by both plants and animals to break down sugars to provide energy in the form of ATP. The energy is processed in the mitochondria.
