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 when blood is filtered by the kidneys. Urine flows from the kidneys down through the ureters and into the bladder. This one-way flow is usually maintained by a âflap valveâ where the ureter joins the bladder. This keeps urine from backing up into the kidney.
