Which of the follo wing bacterial structures share a common evolutionary origin with similar structures in organelles, and provide evidence for Lynn Margulis' Serial Endosymbiosis Theory? a) Transmembrane proteins of the plasma membrane. b) Thylakoids in cyanocbacteria, endomembranes in proteobacteria. c) Ribosomes. d) Peptidoglycan cell wall. e) None of the above. 32. In its dual-host life cycle, the malaria parasite Plasmodium vivax undergoes three different phases each with a very distinct morphology: a sporozoite phase in the gut and salivary glands of the mosquito vector, a merozoite phase that develops in liver cells of the human host, and a gametocyte phase that develops in human red blood cells. Which of the following best explains why the three phases appear so strikingly different? a) Plasmodium vivax itself is a host organism harboring several species of unicellular endoparasitic protists. When Plasmodium is introduced into the bloodstream of human host, it releases the endoparasites, which migrate to the liver and blood cells- b) The genome of Plasmodium vivax contains genes that are expressed differently depending on the conditions of the location of the organism, and the timing of the developmental sequence. c) Plasmodium vivax contains several distinct genomes, each acquired via secondary endosymbiosis. and contain genes that encode the proteins that make up each unique developmental form. The genomes are selectively activated depending on the conditions of the location of the orgonis d) All of the explanations are equally plausible in explaining the morphological differences in Plasmodium vivax e) None of the explanations shown exploin the morphologwal differences in Plasmodium vivax.

Answer 1

28. The fact that both Anacardium occidentale sequence position 3 is an example of: and Mangifera indico both have DNA nucleotide A a) homoplasy b) paraphyly The fact that both Anacardium o nucleotides A at sequence position 3 is an the same family Anacardiaceae e and Mangifera indica both have DNA le of homology. Both belong to convergence. symp 29. What is the significance of the fact that both sequence and C DNA nucleotide? s 1 and 2 involve changes between a G a) The occurrence of G and C in b) The changes involve c) Nucleotide base C is more advanced the respective terminal taxa arose via convergence term d and has a higher likelihood of transition from other base for less common than A-T changes. s. completely separate events ond have no significance whatsoever a hi For all organisms in general, G-C changes are f None of the explanations given adequately expla in its significance. 30. Which of the followin 9 evolutionary processes provide the best explanations for homoplasy? a) Common descent b) Horizontal gene transfer Adaptive radiation. dConvergent evolution. e) More than one of the above. The character that is not present in the common ancestor but is developed independently in more than two organisms is known as homoplasy. They evolve by convergent
