Assume that the phylogenetic assignment of Plasmodium falciparum, the malarial parasite , to the phylum Apicomplexa. Question asked to hypothesize whether the parasite is sensitive to aminoglycoside antibiotics. Introduction: In the phylogenetic tree, species of interest are shown at the tips of the branches of the phylogenetic tree. The divergence of a single group into two descendant groups is shown at the branch point. The most recent common ancestors are found at each branch point. When two species have more related common ancestors, these species are more related, whereas when two species have less related common ancestors, these species are less related. Non-photosynthetic early branching eukaryotic organisms do not have mitochondria as well as chloroplast. This suggests that mitochondria and chloroplast could have appeared in the eukaryotic cells at later evolutionary stages. One of the evolutionary models, endosymbiotic theory, suggests that prokaryotic endosymbionts are converted to a cell organelle. During eukaryotic evolution, heterotrophic eukaryotic cells engulf a photosynthetic eukaryotic cell that survives in symbiosis inside the heterotrophic cell from primary endosymbiosis.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Chlamydomonas should best be classified under: A) One of the Protista Kingdoms of Eukarya Domain B) Archaea domain C) Plant Kingdom of Eukarya domain D) Animal Kingdom of Eukarya domain E) Bacteria domain Explain why

The malarial form infectious for mosquitoes is called aa) gametocyte. b) trophozoite. c) sporozoite.d) schizont. e) merozoite.

In the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.
