Final answer:
Increasing the glomerular filtration rate is the factor that can increase the filtered load of a particular solute in the kidney, as it causes more fluid and solutes to be filtered from the blood into the nephron.
Step-by-step explanation:
Factors Increasing the Filtered Load of a Solute
The question asks which factors can increase the filtered load of a solute in the kidney. The filtered load is the total amount of a substance that passes through the glomerular filter into the nephron each minute. It's influenced by both the glomerular filtration rate (GFR) and the solute's plasma concentration. Notably, increasing the GFR will increase the filtered load because more fluid and solutes are filtered from the blood into the nephron. Other factors, such as reabsorption and secretion rates, do not directly increase the filtered load. Instead, they alter the amounts of solutes that are reabsorbed into the bloodstream or secreted into the filtrate after initial filtration.
In sum, the option that can increase the filtered load of a particular solute is increasing the glomerular filtration rate.
