The term that correctly describes the transfer of organic molecules, inorganic ions, vitamins, and water from the digestive tract's lining into the surrounding fluid is absorption. This process is crucial in digestion because the absorbed materials are subsequently delivered to the body's cells through the circulatory system.
Response:
It would need a lower amount of bicarbonate to neutralize the acid.
Explanation:
Sodium bicarbonate (NaHCO3) is a partially soluble sodium salt that breaks down in water to create a weakly basic buffer solution. It separates in water releasing bicarbonate ions (HCO−), sodium ions (Na+), and H+.
2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)
Buffer solutions are maintained in equilibrium. In a solution with a strong acid, the conjugate base reacts, while other carbonate ions release to form carbonic acid, driving the solution back toward balance.
HA ⇄ H+ + A-
Due to its buffering capability, which is how effectively it stabilizes the equilibrium, less bicarbonate will be required later on to neutralize the acid.
The concept of genetic drift.
