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.
A basis score is a very high score that is usually higher than a bowler's average, usually ranging from 200 to 220. The percentage factor ranges from 80 to 100 percent. To calculate your handicap, subtract your average from the appropriate basis score and then multiply by the percentage factor.
