Urea is made from ammonia filtered out of the blood by the nephrons in the kidney. As ammonia is a highly toxic substance to humans, and humans have moderate water supplies, it undergoes multiple chemical reactions to convert from ammonia to urea which is diluted to urine and excreted out of the urethra.
from the blood, into the kidneys, into the NEPHRONS:
okay so the blood flows through capillaries called the GLOMERIUS (spelling...?) where blood pressure squeezes it out into the the bowl the glomerius is in called BOWMAN's CAPSULE. through the proximal tubule, loop of henle, distal tubule, collecting duct into the RENAL PELVIS thorough the URETER to the BLADDER down through the URETHRA

What happens to the water molecule during condensation?
A hydroxide is taken from the glucose and a hydrogen is taken from the fructose. This leaves the glucose and fructose a place to bond. A hydroxide(HO) and a hydrogen (H) make a water molecule (H2O)
How a water molecule is produced when glucose and frutose undergo a condensation reaction?
A hydroxide is taken from the glucose and a hydrogen is taken from the fructose. This leaves the glucose and fructose a place to bond. A hydroxide(HO) and a hydrogen (H) make a water molecule (H2O)
What happens to the ADP molecule that is produced when cells use the energy in ATP?
Most are taken up by mitochondria and reprocessed into ATP.
What gas is taken through the leaves?

What tissue in addition to the liver is taken from the donor for an orthotopic transplantation?
When an orthotopic transplantation is performed, a segment of the inferior vena cava attached to the liver is taken from the donor as well.
How many carbon dioxide molecules will be made in photosynthesis?
For every six molecules of carbon dioxide (CO2) taken in during the process of photosynthesis, one molecule of glucose (C6H12O6) is produced. This means that six molecules of CO2 are required to produce one molecule of glucose.
Is an air molecule taken into lungs?
yes it can
How is tobacco produced in Virginia?
Tobacco plants grow in fields. Workers strip the leaves from the stalks. The leaves are hung upside down in a barn to dry. If the barn is not heated, burley tobacco is produced. If the barn is heated, flue cured tobacco is produced. Then the tobacco is taken to a warehouse. An auctioneer starts calling out numbers much faster than I can understand. Then he says sold and the farmer's load of tobacco is sold.
