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.
Urine is made as a normal result of metabolism and removal of cellular wastes. Normal urine is sterile and the color can vary depending on what your pet has recently eaten or drunk. If youâre wondering why urine is yellow, itâs due to the presence of a substance called urochrome which is excreted by the kidneys.
