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.
5 pin bowling was originally invented in response to complaints that the bowling ball in ten-pin bowling was too heavy. 5 pin bowling is very popular with children and is an easy introduction to bowling. A perfect score in bowling is 450, which can be obtained by combining more than one strike. A strike occurs when the bowler knocks down all five pins with one bow, and this is worth 15 points.
