Populations have genetic variation.
The environment changes.
Organisms must have specific traits in order to survive and reproduce.
Explanation:
Natural selection is a phenomenon whereby organisms better adapted to their environment are able to survive due to this phenotypic capability.
- Natural selection provides an advantage during an adverse condition for organisms that have a rich genetic variation in their population.
- Also, environmental changes induces natural selection whereby organisms must adapt to changes around.

The periodic table arranges elements in increasing
atomic number from left to right and top to bottom.
Horizontal rows on the periodic table are periods.
Elements in the same period have the same number of
electron shells.
Vertical columns on the periodic table are groups.
Elements in the same group have the same number of
valence electrons.
