Although the operation of natural selection requires that genotypes differ in fitness, for some geneticists it seems easier to understand natural selection than fitness. Partly this reflects the fact that the word “fitness” has been used to mean subtly different things. Here I distinguish among these meanings (e.g., individual versus absolute versus relative fitness) and explain how evolutionary geneticists use fitness to predict changes in the genetic composition

Explanation:
<span>Electrons are not distributed or shared same because of oxyen that is being attracted strongly. Water is a "polar" atom, implying that there is an uneven sharing of electron in its thickness. Water has an incomplete negative charge ( ) close to the oxygen molecule due the unshared sets of electrons, and fractional positive charges ( ) close to the hydrogen particle</span>
