Color is usually some shade of yellow and often varies with the concentration of the sample. The most common color descriptions of normal urine are straw, light yellow, yellow and dark yellow. Amber colored urine is seen in patients with increased bilirubin levels and may indicate hepatitis.
Add the knowledge of bowling's perfect score, 300, and it stands to reason 10 strikes in a row is a perfect 300.
The World Bowling scoring systemâdescribed as current frame scoringâawards points as follows: 1  strike: 30 (regardless of ensuing rolls' results) 2  spare: 10 plus pinfall on first roll of the current frame. 3  open: total pinfall for current frame.
