E) None of the above 21. Match the following: 22. Changes in this surface protein of influenza can A) flora be used to generate vaccines. 23. Suppose the common ancestor of cows and B) coincident whales had an A at one nucleotide site. At this site, whales have G and cows have T. This would be an example of substitution. 24. The phenomenon whereby traits may evolve C) pseudogene independently in unrelated species because the species are subject to similar selection pressures is known as -evolution. 25. A sequence of DNA that arose from a gene D) Hemagglutinin duplication and is no longer functional is known as a 26. The entire composition of plants in a given E) convergent locality is known as itsExplanation / Answer
18) The correct option is D. prokaryota.
The cell wall of prokaryote contains peptidoglycan belongs to Bacteria and Archaea domains.
19) The correct option is B. heteromorphic.
Heteromorphic have two or more different forms at different stages in the life cycle.
20) The correct option is B. gene duplication.
Proteins can acquire new functions via the process of gene duplication.
21) The correct option is C. paralogs.
Paralogs are homologous genes. They have evolved by the process of duplication and code for protein with similar but not identical functions.
