The bicarbonate buffering system in the blood is the most important buffering system in the ECF. Bicarbonate ion and carbonic acid are the key components of this buffering system. The weak base <u>bicarbonate</u> serves to buffer the strong acid <u>H+</u><u>.</u> The buffer to the strong base <u>OH-</u><u> </u>is <u>carbonic acid</u>. The byproduct of these reactions is <u>water.</u>
Explanation:
A buffer system utilizes chemical buffers and resists any changes in the pH and adjusts acidity and alkalinity of the medium by binding or releasing H+ ions accordingly.
A bicarbonate buffering system in the ECF regulates the bicarbonate level and maintains the normal acidity level of blood.
Sodium bicarbonate reacting with a strong acid (HCl) produces a weak acid (carbonic acid) and sodium chloride. A strong base like (NaOH) reacts with carbonic acid producing bicarbonate and water.
NaHCo3 + HCl → H2CO3 + NaCl
H2Co3 + NaOH → HCO3 + H20
The acidity of the blood is regulated by maintaining the ratio of bicarbonate and carbonic acid at 20:1 under normal conditions through the bicarbonate buffer system. The carbonic acid level is regulated by the respiratory system; while carbonate level is regulated by the renal system.
Answer: protons
Explanation: atoms of each element contain a characteristic number of protons
Answer:
Eukarya - (D)
Explanation:
Organisms belonging to the plant kingdom are eukaryotic and multicellular organisms. They have a distinct cell wall made of cellulose. Cells are organised into true plant tissues. Plants contain plastids and photosynthetic pigments such as chlorophyll.
Answer: The correct answer is- all the sugar maple trees that are present in a state park.
Population can be described as a group of individuals belonging to a particular species, which inhabit a particular area.
In this question, last option that is all the sugar maple trees that are present in a state park correspond to a particular population.
Other options have organisms occupying different areas across the world.
