Answer:
have the same number of electron energy levels
Explanation:
All of the elements in the same period have the same number of atomic orbitals that are occupied by electrons that are in constant motion. For example the elements in the first period have one orbital for its electrons. The elements in the second period have two orbitals for their electrons. As you move down the table, every row adds an orbital. At this time, there is a maximum of seven electron orbitals.
Answer:
The correct answer is option B) "stabilizing selection".
Explanation:
Stabilizing selection is a type of natural selection at which mean traits are favored by nature instead of extreme values. In this case at which sparrows with average-sized wings survive severe storms better than those with longer or shorter wings illustrates stabilizing selection. It its believed that this type of selection is the most commonly found in nature, since most traits have no extreme values in most of the species.
