What does the respiratory system eliminate when there is an excess of hydrogen ions in the body?
qwelly [4]

Answer:by breaking down carbonic acid into carbon dioxide and water.

The carbon dioxide is expelled from the body

Explanation:the body is able to maintain a constant internal environment through hoemostatis.one of such control is the acid-base balance in the body.

It does this by regulating the amount of hydrogen ions in the blood.A low pH indicates an acidic condition and a high pH indicates an alkaline condition.

The human blood has a pH of 7.35---7.45.it is slightly alkaline and needs to keep this range constant.

The lungs and kidneys involved in regulating the body pH.

When there is excess hydrogen ion in the blood, bicarbonate ions combine with the hydrogen ions to form carbonic acid . this carbonic acid breaks down into water and CO2 .the co2 is expelled from lungs through gaseous exchange.

When the accumulation of acid in the blood is high,the pH drops below 7.35 and this is called respiratory acidosis.

When there is excess alkaline in the blood,the pH goes beyond 7.45 and this is called respiratory alkalosis.

Freckles is dominant over no freckles. what percentage of offspring would be predicted to have freckles if the father was hetero

Father: Ff

Mother: ff (She has no freckles, meaning she does not have the dominant allele)


F f

f Ff ff

f Ff ff


The count would then be 2/4 with freckles and 2/4 without freckles. So the percentage of would be 50% with freckles and 50% without freckles.
