Sonar sends sound waves to the bottom that bounce back and tell the machine how far away the object is based on how long it takes for the sound wave took to come back.
Answer:
Because lack of carbon dioxide causes the lack of acidic HCO₃⁻ which help to the regulation of the blood's pH.
Explanation:
Hello.
In this case, since the presence of carbon dioxide in blood regulates the pH of blood by maintaining it at about 7.35 to 7.45 (slightly basic) due to the equilibrium shown on the attached picture by which the yielded HCO₃⁻ ions low down the pH because the lack of CO₂ cause a condition known as respiratory alkalosis in which the pH of the blood significantly increases.
Thus, that condition causes symptoms such as confusion, hand tremor, lightheadedness., muscle twitching, nausea, vomiting and others.
