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 inability of a cell to take in or produce sugars prevents the synthesis of carbohydrates and nucleic acids.
Answer:
B) Lysosome
Explanation:
Lysosomes are organelles within eukaryotic cells, characterized by a covering of double membranes and an internal composition of hydrolytic enzymes. These enzymes, commonly referred to as digestive enzymes, play important roles in catalyzing the breakdown of proteins and various complex molecules. Examples of hydrolytic enzymes located within lysosomes include proteases, glycosidases, and phosphatases.
The correct choice is option (B). An ecosystem is generally described as a biological community consisting of living organisms that interact with their environment to thrive. Various factors, including rainfall, temperature, and elevation, dictate the specific ecosystem type. Ecosystems rely on two primary processes: nutrient recycling and energy flow. Nutrients like carbon, iron, and sulfur are drawn from organisms and plants, with decomposers replenishing these nutrients in the soil, allowing plants to use them before they are transferred to consumers. Simultaneously, energy is converted from one form to another, with about 10% of it transitioning between trophic levels, while the rest dissipates into the environment. These dual processes continuously operate together, facilitating recycling and utilization.
