Question

glomerular filtrate contains small, dissolved molecules in approximately the same concentration as ______
fill in the blank

Explanation:

Glomerular filtration in the kidneys allows small, dissolved molecules (like ions, glucose, urea) to pass from blood plasma into the glomerular filtrate. The filtrate's small - molecule concentration matches that of blood plasma because the filtration membrane is permeable to these small solutes, while larger molecules (like proteins) are mostly excluded.

Answer:

blood plasma
