The relative atomic mass of sodium is calculated by dividing the atomic mass of sodium by the unified atomic mass unit, which is 1.66*10-27 kg. The number of 23 amu means that a normal, or stable, sodium atom weighs 23 unified atomic mass units.

Answer:
<em>The correct options are D. dark-colored, small-sized snails and F. dark-colored, large-sized snails</em>
Explanation:
Evolutionary studies show that those organisms are able to survive and reproduce which are better adapted to live in an environment. Gradually, the organisms that are better adapted to live in an environment increase in number and those that are not better adapted will decrease in population.
As Avian snail kites feed on light- colored apple snails and Avian limpkins feed on medium- sized apple snails, this means that these species are not better as they can be easily captured by their predators.
The dark colored, small- sized snails and dark- colored, large- sized snails will be better adapted to live in the environment as they will not attract the predators. Hence, they will survive and reproduce.
