Chromosomes occur in pairs (in most somatic cells) since one member of each pair comes from the mother and the other from the father. In most prokaryotes, the chromosome is usually a circular strand of DNA; hence, the entire genome is carried on only one chromosome.
Thus, an average diet of 1,900 calories per day would dictate an intake of 1,900 ml (approximately 64 ounces) of water. However, people interpreted this as a recommendation to drink 1,900 ml of pure water, forgetting the fact that water is also found in abundance in the other liquids and foods we consume.
Another method you can use to determine how much water you should drink each day is by dividing your weight in pounds by two, according to the Public Broadcasting System. The resulting number is the amount of water in ounces you should drink each day. If you weigh 150 pounds, you should consume at least 75 ounces of water per day. This is a little over nine cups of water daily.
