Answer:
b. The two bacterial strains have different phenotypes.
Explanation:
In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.
Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.
Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.

Answer:
E. O. Wilson say polygamy is natural
Explanation:
There are a number of ways to prove polygamy is natural, actually. The most meaningful one would be when you literally look at the number of mates that are simultaneously maintained by a member of one sex. In the case of polygyny, which is male harem formation, you simply look at the number of females in an average harem.
You can also look it anatomically. If you look at those species that are highly polygynous, in which many females are mated to just one male, we find that they're actually highly sexually dimorphic, and there's a really close one-to-one correspondence between the degree of polygyny in terms of number of mates and the degree of sexual dimorphism.
