Answer:
D. increase of carbon dioxide
Explanation:
Breathing is automatic and is controlled subconsciously by respiratory center at base of brain. It continues during the time of the sleep and even when the person is not in conscious. Sensory organs in brain and in aorta and the carotid arteries monitor blood and sense the oxygen and the carbon dioxide levels. <u>Usually, increased concentration of the carbon dioxide is the strongest stimulus for the breathing to occur more deeply and more frequently. </u>
When carbon dioxide concentration in the blood is high, the brain increases the frequency and the depth of breaths.

Oxidation half reaction is written as follows when using using reduction potential chart
example when using copper it is written as follows
CU2+ +2e- --> c(s) +0.34v
oxidasation is the loos of electron hence copper oxidation potential is as follows
cu (s) --> CU2+ +2e -0.34v
Noble gas configuration for Li : [He]2s¹
<h3>Further explanation
</h3>
In an atom, there are levels of energy in the shell and sub-shell
This energy level is expressed in the form of electron configurations.
Lithium with atomic number 3, then the electron configuration:
1s²2s¹
And for noble gas configuration or it can be called Condensed electron configurations :
[He]2s¹
