Which of these correctly describes the steps you'd take to find the molar mass of water (H:O)? A. Multiply the relative atomic mass of hydrogen by 2. Add the product to the relative atomic mass of oxygen.
B. Multiply the atomic number of hydrogen by 2. Add the product to the atomic number of oxygen.
C. Multiply the relative atomic mass of oxygen by 2. Add the product to the relative atomic mass of hydrogen.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
