    Because, at first scientists thought that atomic mass is more fundamental property than.... But the reality was vice versa It is visible that they thought so as all scientists how tried classification earlier used atomic mass itself.

    Ultra filtration Reabsorption Secretion

    0Thank You

    Rithika Gautam 5 years, 1 month ago

    1. Filtration: Filtration of blood takes place in Bowman’s capsule from the capillaries of the glomerulus. The filtrate passes into the tubular part of the nephron. This filtrate contains glucose, amino acids, urea, uric acid, salts and a major amount of water. 2. Re-absorption: As the filtrate flows along the nephrons, substances such as glucose, amino acids, salts, and water are selectively re-absorbed into the blood by capillaries surrounding the nephron tube the leadule. The amount of water re-absorbed depends on the need of the body and also on the amount of wastes to be excreted. 3. Urine: The filtrate which remains after re-absorption is called urine. Urine contains dissolved nitrogenous waste, i.e. urea and uric acid, excess salts and water. Urine is collected from nephrons by the collecting duct to carry it to the ureter.

Here if the mass is same then the length should also be equal but the length is not equal and so as to satisfy the given part the areaB=twice area A And we put the values in the formula of resistivity we find the ratio to be 1:4
