The Following are Examples of Challenges for Classification of Eukaryotes

Question

The following are examples of challenges for classification of eukaryotes, EXCEPT
A) eukaryotic chromosomes are located inside the nucleus.
B) eukaryotes have experienced multiple endosymbiotic events.
C) genome size and complexity has delayed completion of genomic sequences.
D) for superficial similarity in form and habitat in distant taxa leading to convergent evolution.
E) within a clade, some cells have lost structures through reductive evolution; others have not.

Accepted Answer

The fact that eukaryotic chromosomes are located inside the nucleus is a defining characteristic of eukaryotes and is therefore not a challenge for their classification. The other options are all challenges for the classification of eukaryotes.
