WebSolution. The correct option is B decreases. The amount of water sent out through urine depends on the water required by our body. During hot days, our body requires a lot of water. So, even if we drink a lot of water, the amount of urine produced is less. During cold days, our body sends out a lot of water, so the amount of urine produced is more.

WebUrine becomes hypertonic because of the loop of Henle and the collecting duct. Salt passively diffuses out of the lower portion of the ascending limb. The upper part of ascending limb actively transports salt into the tissue of the renal medulla. Urea leaks from the lower portion of collecting duct and contributes to a high solute concentration. Web26 jul. 2024 · Hydrogen ions (H +) are produced by the action of the enzyme carbonic anhydrase and react with ammonia (NH 3+) to produce ammonium (NH 4+ ). Most ammonia is produced in the process of deamination and oxidative amination of gills. However, due to these reactions in the liver, small amounts of ammonia is produced.
