actually , renal plasma flow rate is about 700 ml per minute and glomerular filtration rate is about 125 mL per minute.. hence,

the average filtration percentage comes out near 18% .. so..for the 1st, answer is 20%.ie 3rd...

for the next one..cholesterol is the answer.. every molecule which is small in size can enter the renal space ( renal calculus) .. but u know that cholesterol is a very bid molecule.. and so are proteins.. and u can include other macro molecules too..

hence, these are not present in the renal space in normal conditions as they dont pass thro the filtration pores of nephrons...

ANS is 3 the filtrate contains all the constituents of blood except blood cells and plasma proteins nearly 15-25% of plasma flows through glomerulus.plasma here mainly means water and few solutes.

ANS is A cholesterol its bcoz calculi are mainly salt crystals formed due to slow accumulation.salt molecules can easily enter inside renal pathbcoz of smaller size .all these things are just opposite in case of fatty cholesterol molecule

graviton,,,in the end,,,it doesnt even matter
