Q. The human kidney
A) Is responsible for the storage of nutrients such as glycogen
B) Concentrates the urine by actively transporting water out of the filtrate
C) Produces more dilute urine when the collection ducts become less permeable to water
D) Responds to antidiuretic hormone by increasing urine output
Explanation
From the distal convoluted tubule, the filtrate enters the collecting tubule, where further reabsorption of water takes place. Now the filtration become more concentrated which place. Now the filtration become more concentrated which makes the filtrate hypertonic. When the collecting duct become less permeable to water it produces more dilute urine.
