Nitrogenous Waste Removed from Body
Simple aquatic animals excrete ammonia in surrounding water by diffusion. In higher animals ammonia is converted into less toxic compounds such as urea, and uric acid.
Urea is excreted out in the form of urine. Uric Acid is produced in insects, reptiles and birds. It is excreted out in the form of crystals with little water..
Note: Most of the Chinese do not speak English. Even at the international airport. If the foreigner needs any help, the airport employees in two of the cases of three will look at him with huge, understandable eyes and try to call their more or less able to speak in an incomprehensible language to a colleague. What can we say about ordinary provincial residents? Dormitories for Chinese and foreign students are divided. And thank God, because Chinese students live for 6-8 people in one small room! The soul in their hostels is not there, so everyone goes to public showers, which, fortunately, are on the territory of the university. There is no kitchen, there is no hot water either, the heating is practically non-existent, and the total light turns off at 11:00 pm, at the same time, when the doors to the building are closed. Dormitories for foreign students look completely different: 1-2 people in a spacious room, own bathroom, air conditioning, TV, shared kitchen – in general, welcome to China.
