Final answer:
Glomerular filtration typically happens at a rate of about 125 mL/min in males and 105 mL/min in females, making option 'a' the correct answer.
Step-by-step explanation:
Glomerular filtration normally occurs at a rate of approximately 125 mL/min in males and about 105 mL/min in females. The glomerular filtration rate (GFR) indicates kidney function and is determined by the amount of blood filtered by the glomeruli of the kidneys each minute to form urine. High blood pressure and specialized membranes in the afferent arteriole of the glomerulus facilitate filtration, allowing most solutes, except large molecules like proteins, to pass through into the filtrate by passive diffusion.
