the dumping of large amount of sewage into the sea can cause oxygen in the water to be used up......how oxygen is used up?

Oxygen-consuming wastes comprise of raw sewage from municipalities and other wastes from paper mills, tanneries, food-processing plants and agriculture; these cause a proliferation of aerobic decomposers who consume dissolved oxygen (DO) in water m..

To Demonstrate Aerobic Respiration The apparatus shown is called the respiroscope that is used to demonstrate respiration. Few germinating seeds are taken in the bulb of the respirometer. The tube is inserted into a beaker containing mercury. A pellet of KOH is introduced into the set..

Oxygen is transported in a combined state. The haemoglobin pigment (Hb) has an affinity for oxygen. In the lungs, it combines with oxygen and forms HbO 2 , oxyhaemoglobin...
