Two major pieces (queens or rooks) can easily force checkmate on the edge of the board. The process is to put the two pieces on adjacent ranks or files and gradually force the king to the side of the board, where one piece keeps the king on the edge of the board while the other delivers checkmate.
Urine is mostly water (about 95% water), however, the rest of the contents of urine can vary depending of what youâve eaten, drank, breathed or been exposed to. The remainder of urine usually consists of urea, uric acid, ammonia, hormones, dead blood cells, proteins, salts and minerals, and toxins.
Normally, only water soluble substances are excreted in the urine. Urine is produced by the kidneys as a process of cleaning the blood and excreting the unwanted soluble waste products from the body. The kidneys filter out the waste products such as toxins, excess water and mineral salts from the bloodstream.
