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.

Excess water is removed from your body through sweating as well as urination. MedlinePlus recommends drinking six to eight 8-ounce glasses per day. While a gallon of water is double the recommended intake, the excess will simply be excreted by your body.
