Explanation: Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Uric acid is the chief nitrogenous waste present in the urine especially of birds, reptiles, and insects, whereas humans (mammals) & frogs excrete urea. And fishes, excrete ammonia. Formula: Uric AcidRead more

Explanation: Nitrification is the process that converts ammonia to nitrite and then to nitrate and is another important step in the global nitrogen cycle. Most nitrification occurs aerobically and is carried out exclusively by prokaryotes.

Explanation: Terylene and nylon are synthetic fibres produced by a process of polymerisation. Terylene is a polyester and nylon, a poyamide. Silk is purely a natural product obtained from silk worms. Rayon is a man-made material which consists of purified cellulose in the form of long fibres. CellulRead more

Silk is purely a natural product obtained from silk worms.
Rayon is a man-made material which consists of purified cellulose in the form of long fibres. Cellulose occurs in the cell wall of plants. Rayon fibre is chemically identical to cotton but has a shine like silk. Since it is basically derived from a natural source (cellulose) it is called a regenerated fibre.
