Answer:
A potometer measures water loss from leaves. A bubble potometer measures the rate of water loss from a plant by transpiration. A weight photometer measures the amount of water lost by a plant through transpiration. The washing line method is used to prove that most water loss occurs from the lower surface of the leaf.
potometer' (from Greek ποτό = drunken, and μέτρο = measure), sometimes known as transpirometer, is a device used for measuring the rate of water uptake of a leafy shoot which is almost equal to the water lost through transpiration. The causes of water uptake are photosynthesis and transpiration

Answer: 
Nitrogen containing waste consist or urea, ammonia, uric acid and creatinine, which is eliminated as urine by the kidney.
Explanation:
Nitrogenous waste is a by product of protein metabolism that takes place in the liver. It is transported to the kidney where its filtered by the nephron and excreted in form of urine in mammals, uric acid in reptiles.
