The average expiratory reserve volume or ERV is 810.
<h3>What is expiratory reserve volume?</h3>
- Expiratory reserve volume or ERV is the amount of air that is exhaled forcibly.
- This can be measured using a spirometer and is used to detect restrictive lung diseases.
- It is the maximum amount of air that can be exhaled after normal tidal volume is exhaled.
- Respiratory volume is the volume of air which is either inhaled, exhaled or stored in your lungs.
- The doctors estimate the reserve volume with the help of spirometer to determine some lung diseases.
- Once diagnosed with a lung disease, spirometry is used to monitor it.
- Here, 3 readings of ERV are taken, calculate the sum of the these and divide by 3 to calculate the average ERV.
- ERV= (800+ 850+ 780)/ 3= 810

Answer;
-Because the chemical groups that form hydrogen bonds are in the wrong positions.
Explanation;
-A base pair is any of the pairs of nucleotides connecting the complementary strands of a molecule of DNA or RNA and consisting of a purine linked to a pyrimidine by hydrogen bonds.
-The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA or in hybrid DNA-RNA pairing. A mutation in the sequence of DNA that makes an adenine to be paired with a cytosine results to an unstable interaction because the chemical groups that form hydrogen bonds are in the wrong positions.
To prevent blood flowing back after each heartbeat. They ensure that the blood flows only in one direction (back to the heart).
I think in real life because you get to see how they act and i have been on three trips i know that this is not related but I've been to Egypt and Italy and china and i am in 7th grade so ya. I think seeing animals and things in real life is the best thing to do overall.
<span>Suffocation is a most leading reason of death in grain storage
bins. Grain handling industry is a high hazard industry where workers can be
exposed to numerous serious and life threatening hazards. These hazards
include: fires and explosions from grain dust accumulation, suffocation from
engulfment and entrapment in grain bins, falls from heights and crushing
injuries and amputations from grain handling equipment. </span>
