Lewis Structure:An atom forms a single covalent bond with another atom through the atoms sharing one valence electron pair. If the starting atom originally contains several valence electrons, then it can form multiple covalent bonds to different peripheral atoms. This is the basis for many simpl...

and presumably still clothed in his human flesh. A possible explanation is that in most Middle Eastern languages (notably Aramaic) there is no easy way of distinguishing between the statements "A is B" and "A is like B" or "A represents B". So, even assuming that Jesus did utter the ...

One possible explanation is that the levels of TNF-a reached in both models were very similar and lower than those measured in the absence of clodronate depletion. Alternatively, the fact that our PTP1B KO mice lack of this enzyme in all tissues, including the liver, cannot exclude a ...
A potential explanation may exist elsewhere like the genetic susceptibility [72–74]. Since we failed to vali- date it in the US NHANES, and few related studies are available now, the inherently complex relationship may wait for further exploration and validation. Certainly, those with low SES ...
