Explanation

The other options, although close, do not accurately reflect this average weight. The options of 140 grams and 150 grams are slightly below the average, while 130 grams is significantly lower and unlikely.

About Kidney and Urinary System
The kidney and urinary system remove nitrogenous wastes, regulate water and ion balance, and help maintain blood pH through filtration, selective reabsorption and secretion. Questions cover nephron structure, ultrafiltration, the loop of Henle, collecting ducts, urine formation and the roles of ADH and aldosterone, while distinguishing excretion from egestion.
