Answer:
(B). The drug is reabsorbed.
Explanation:
Renal clearance rate determines the excretion of drugs into the urine during excretion. It is used to study the main process associated with a drug's renal excretion.
When the renal clearance rate is lower than GFR (glomerulus filtration rate), the drug is absorbed in the renal tubules. When the renal clearance rate is higher than GFR, the drug is secreted into the urine. When the renal clearance rate is equal to the GFR, the drug is neither reabsorbed nor secreted.
As for given drug, renal clearance is 20 ml/min (less than GFR), this drug will reabsorbed.
Thus, the correct answer is option (B).
Since the wheelbarrow is filled with soil, that adds more weight to it. Which means you would need to use more strength/force.
When the wheelbarrow is empty, it has less weight so you would use less force.
