These structures are known as Ribosomes.
Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

One of the challenges that scientists face when classifying a new fossil is that any tiny detail is all that separates one species from another. Further exploration is required to identify another set of characteristics that may help in deciding which organism belongs or create a new class.
Answer:
the spring time is when they call for mates
Natural selection or survival of the fittest can cause a major evolution as the species at risk need to stay alive and therefore need to become more adapted to the situation at hand. The species can evolve through generations to become more crafted to the predatorial habits of their predators. If the females are less at risk than the males then the males might evolve to become more protected or if some of the species live in a different situation maybe not even that far away, that can have a big impact on the evolutionary habits of the species at hand.
I hope I'm right
