Answer:
Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
Explanation:
The concentration expressed in parts per million is 782 ppm.
<h3>What is Parts per million?</h3>
It is calculated by dividing the mass of the solution by the mass of a solute present in one million (10⁶) parts.
<h3>Calculation for units in ppm:</h3>
Given:
Mass of blood alcohol = 80 mg/dL = 80 x
g/mL
Density of blood plasma or Mass of blood plasma = 1.023 g/mL
Concentration in ppm = (Mass of alcohol/Mass of plasma) x 
= (80 x
g/mL/ 1.023 g/mL) x 
= 782 ppm
Hence, the concentration expressed in parts per million is 782 ppm.

Hi! Okay I’m going to be answering this from experience. an Appendicitis attack would be extreme lower right quadrant pain, fever, vomiting, and tenderness in the area. that would need to be addressed immediately otherwise you will die. Now a cyst on your ovary can be one, just a cyst, or two, PCOS (poly cystic ovary syndrome). Both a singular cyst and PCOS can be treated with birth control options, so i don’t think that’s the causing factor. Both can cause painful ovulation, lower pelvic / back pain, irregular periods, and excessive hairiness. One cyst would usually go away in a couple months, where PCOS does not
