No,
The DCT is impermeable to water.
Solutes (Na and Cl) are absorbed from the DCT.
As a consequence the osmolality of tubular fluid DECREASES as it moves through the distal convoluted tubule, from ~100mOsm/L at it exits the ascending limb of the loop of Henle to around 70mOsm/L as it enters the collecting duct.
No, the collecting duct is the site where the filtrate from multiple nephrons is collected and the final adjustments to urine concentration are made. The distal convoluted tubule drains into the collecting duct.
The parts of a nephron in order are the renal corpuscle (glomerulus and Bowman's capsule), proximal convoluted tubule, loop of Henle (descending and ascending limbs), distal convoluted tubule, and collecting duct.
Aldosterone acts on the distal convoluted tubule and collecting duct in the kidney to increase sodium reabsorption and potassium secretion.
The maximum reabsorption of water occurs in the proximal convoluted tubule of the nephron in the kidneys. Approximately 65-70% of the filtered water is reabsorbed here, along with a significant amount of solutes. Additional water reabsorption takes place in the loop of Henle, distal convoluted tubule, and collecting ducts, but the proximal convoluted tubule is where the majority occurs.
From the glomerulus, the sequence of the nephron is proximal convoluted tubule, loop of Henle (descending and ascending limbs), distal convoluted tubule, and collecting duct.
The distal convoluted tubule or the collecting tube.
The distal tubule
Proximal convoluted tubule, Loop of henle and Distal convoluted tubule.
Proximal convoluted tubules have brush borders or microvilli on the inner edge of the tubule. Distal convoluted tubules do not have this structure.
the three main portions of the renal tubule are the proximal convoluted tubule, the loop of henle, and the distal convoluted tubule. the proximal convoluted tubule is the first portion. The proximal (convulated) tubule.

Bicarbonate.
The parts of a nephron in order are the renal corpuscle (glomerulus and Bowman's capsule), proximal convoluted tubule, loop of Henle (descending and ascending limbs), distal convoluted tubule, and collecting duct.
The proximal convoluted tubule is closest to the glomerular capsule. The distal convoluted tubule is farther away.
