Calcium oxide is a basic oxide because when metals reat with oxygen they form basic oxides
"The first and second hominids were able to mate and produce offspring, but the first and third hominids could not." <span>Although that might be the case, it might also not. "More similar" needn't be 'similar enough' (disregarding the fact that all homonid specimens involved could happen to share the same sex). </span>
<span>"The first and second hominids shared the same geographic location, while the third was isolated." </span>
<span>That information would be revealed by the geographic location they came from. </span>
<span>"The first and second hominids most likely became extinct before the third hominid species." </span>
<span>Perhaps or perhaps not. As ancestral lineages can survive for longer than descendant lineages, it needn't apply. Still, I suppose the non-existent law of averages provides some sort of justification for the use of "Most likely". </span>
<span>"The first and second hominids have a more recent common ancestor than the first and third hominids." </span>
<span>Assuming these are all in the same neat lineage, then the most recent common ancestor of the first and second is also the most recent common ancestor of the first and the third.</span>
As phosphorus is in need of 3 electrons to gain a stable valence electron configuration, its most likely to bond covalently; share valence electrons with another atom to become stable.
The complementary side would read TACGGCA
