<h2>Respiratory Acidosis</h2>
Explanation:
- <em><u>The need for a stronger than normal stimulus in order to trigger an action potential</u></em>
- The reasons for impaired respiration include aviation route obstacle, discouragement of the respiratory focus in the<em> brain stem, lung disease, and medication overdose</em>
- The <em>hypoventilation </em>brings about raised c<em>arbon dioxide levels in the blood, the H levels increment, and the pH estimation of the blood decreases</em>
- Respiratory acidosis is a health related crisis in which diminishes the <em>blood's pH</em> (a condition by and large called acidosis) and the ventilation increases the <em>concentration of carbon dioxide in the blood</em>
The correct option is D.
A scientific theory refers to an in depth explanation of a specific observed phenomenon while a scientific law refers to a statement about a particular observed phenomenon. Scientific laws are usually presented in form of mathematical expressions for the observed phenomenon; examples of these are Newton's law of gravity, Mendel's law of independent assortment, etc. Scientific law basically describes the observations that are made and these observations are usually similar to other related observations.
