Sodium and potassium are essential electrolytes that maintain water distribution in the body but are lost through sweat during exercise. Gatorade contains 160 milligrams of sodium and 45 milligrams of potassium per serving, while Powerade contains 150 milligrams of sodium and 35 milligrams of potassium per serving.
The number of chromosomes that a butterfly has varies widely. The  wood white butterfly can have anywhere from 56 to 106 chromosomes.  Some butterflies have as many as 380.
Exactly how many chromosomes we are talking about depends on the species. A mosquito has 6 chromosomes, a pea plant has 14, a sunflower 34, a human being 46, and a dog 78. Closely related species tend to have a similar number of chromosomes. For example, chimpanzees, our closest cousins, have 48 chromosomes in each of their cells. But aside from this general rule, there is very little rhyme or reason to how many chromosomes a species has.
