i would have to say B or C. leaning more one C though, i hope i'm right haha. best of luck!! :D
Answer:
<u>C. The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.</u>
Explanation:
- As suggested by the Alfred Wegener, the plates of the South America and the African plants had a similar geologic history and thus shared a common tectonic boundary and hence validate the proof of the superclass and the drifting of the plates at various time zones.
- Thus after the 1960s the plate tectonic theory came into the limelight and was heavily recognized to be fit the works of the drifting of the continental landmasses.
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.

The viruses that lie dormant in host cells until ready to multiply use : Lysogenic cycle
During the lysogenic cycle the virus do not kill the host. It integrate it's dna with the host's so it could lie dormant until it ready to multiply
Hope this helps
