How would hypertonic urine be produced from an isotonic blood plasma?
# Water is reabsorbed all along the nephron. # Urine becomes hypertonic (salty) because of the loop of Henle and the collecting duct. # Loop of Henle # The descending limb of the loop of Henle can't absorb salt, and the ascending limb can't absorb water. # Salt passively diffuses out of the lower portion of the ascending limb. # The upper part of ascending limb actively transports salt into tissue of the renal medulla. # Increase in salt in the direction of the inner medulla. # Urea leaks from the lower portion of collecting duct and contributes to a high solute (salt) concentration. # Water leaves descending limb of the loop of Henle, returning to the blood. # Urine is hypertonic to blood.

Is D5W Isotonic or Hypertonic?
Normal Saline Solution in 5% Dextrose or D5NSS is a hypertonic solution. It can be used for the temporary treatment of shock if plasma expanders are not available. However, do not administer this IV for clients with cardiac or renal conditions.
Why did plant cells plasmolyze when immersed in a hypertonic solution?
Plant cells plasmolyze when immersed in a hypertonic solution when the cell wall detaches under high pressure causing water to be lost. The more solutes a cell has, the less water becomes available.
When an ADP molecule gains a phosphate it becomes an ATP molecule. This process is called?
This process is called phosphorylation.
What is a example sentence for hypertonic solution?
When the concentration of solutes is more, it becomes a hyper-tonic solution. Salt can act like a solute in this case.
During DNA replication what does the DNA molecule do?
It becomes duplicated.
Loss of electrons from a molecule is called?
Ionization, it becomes a cation
