Vedclass · Answer

(D) $(i)$ Vertebrate brains show structural similarities due to common ancestry,representing homologous organs and divergent evolution. This is correct.$(ii)$ Vertebrate hearts (e.g.,fish,amphibians,mammals) are homologous organs,not analogous. They show divergent evolution,not convergent. This is incorrect.$(iii)$ Thorns of Bougainvillea and tendrils of Cucurbita are modifications of axillary buds. They are homologous organs showing divergent evolution. This is correct.Therefore,both $(i)$ and $(iii)$ are correct matches.

$(i)$ Vertebrate brain	Homologous organ,Divergent evolution
$(ii)$ Vertebrate heart	Analogous organ,Convergent evolution
$(iii)$ Thorn of Bougainvillea and tendrils of Cucurbita	Homologous organ,Divergent evolution

Column-$I$	Column-$II$
$(1)$ Mutation	$(a)$ Change in population allele frequencies due to chance alone.
$(2)$ Gene flow	$(b)$ Difference in survival and reproduction.
$(3)$ Natural selection	$(c)$ Immigration,emigration change allele frequencies.
$(4)$ Genetic drift	$(d)$ Source of new alleles.
