Question

Asate as the 1980's, all eukaryotes containine alla were classified within a phylum called Masophora a contained such diverse forms as helena Val dinoflagellates, choanoflagelates, etc. Based upon the more modern classification found in your text, such a classification would be A) monophyletic B) paraphy letie C) polyphyletic Daphyletie Figure 2 A > DHE 12.) Uncommon occurrences can help us understand evolutionary events, as shown in figure 2 above. Which of the following statements explains the logic of this approach? A) Organisms with the DHFR-TS gene fusion evolved convergently. B) The DHFR-TS gene fusion provided an adaptive advantage to the organisms that contained it. C) Because the DHFR-TS gene fusion likely occurred only once, all organisms with the mutation most likely have a common ancestor with the mutation D) "Reverse evolution" does not occur. 13.) Both fungus-farming ants and their cultivated fungi can synthesize the same structural polysaccharide(s) from glucose. This these) polysaccharise(s) would be A) chitin B) glycogen C) starch Diboth &

Answer 1

Answer 11:

According to question,the grouping consists of all eukaryote who possess falgella ( used for locomomotion). The organisms included in the group - Euglena, Volvox, dinoflagellates, etc. doesn't include their recent common ancestor.

Such a grouping which includes organisms based on a particular common trait, but doesn't include a common ancestor is called a polyphyletic grouping.

Hence, the correct choice should be:

(C) Polyphyletic.
