Which important mineral cannot be reabsorbed by the kidney?Group of answer choicesSodiumChloridePotassiumChloride and potassium

The kidneys are capable of reabsorbing important minerals such as sodium, chloride, and potassium. However, the reabsorption of these minerals is not always 100%. The amount reabsorbed can vary depending on a variety of factors, including the body's current needs and the concentration of the minerals in the blood.

1. Sodium: The kidneys reabsorb about 99.5% of the sodium filtered by the glomeruli. The remaining 0.5% is excreted in the urine.

2. Chloride: Like sodium, the kidneys reabsorb a large amount of the chloride that is filtered by the glomeruli. The exact percentage can vary, but it is typically around 99%.

3. Potassium: The kidneys also reabsorb a significant amount of potassium, but the percentage is lower than for sodium and chloride. On average, the kidneys reabsorb about 80-90% of the potassium filtered by the glomeruli.

4. Chloride and Potassium: As mentioned above, both of these minerals are reabsorbed by the kidneys, but not always 100%.

So, all the minerals mentioned in the question can be reabsorbed by the kidneys to some extent. The question might be referring to a specific context or condition where reabsorption of a particular mineral is impaired or prevented. In normal conditions, all these minerals can be reabsorbed.
