Concept explainers
a)
Interpretation:
The group should be determined to which Z belongs in the following Lewis structure and along with an example of such a compound or ion which actually exists.
Concept Introduction:
Number of lone pair and bond pair electrons on an atom can give the number of valence electrons. This is indicated by the group number of an atom.
Group number is equal to the valence shell electrons of an atom or electrons present in the outermost shell. Valence shell electrons of the atom take part in the bonding.
Formal charge on an atom is defined as the charge assigned to the atom in a molecule. It is assigned to an atom or molecule by assuming that the electrons in
Formal charge is equal to

He plotted that data in the graph below to determine if height was a heritable trait. A. Is height a heritable trait? If yes, what is the heritability value? (2 pts) B. If the phenotypic variation is 30, what is the variation due to additive alleles?
