In its dual-host life cycle, the malaria parasite Plasmodium vivax underg ch with a very distinct morphology: a the g oes three different sporozoite phase in the gut and salivary glands of the mosquiteo d merozoite phase that develops in liver cells of the human host, and a gametocyte phase that kingly different? a) Plasmodium vivax itself is a host organism spe kingly ditteman red blood cells. Which of the following best explains why the three phases appear so protists. When Plasmodium is introduced into the bloodstream of human host, it releases the conditions of the location of the organism, and the timing of the developmental sequence. protists. When Plasmodlium is introrsenarig several species of unicellar endoparasitic. endoparasites, which migrate to the liver and blood cells. b) the genome of Plasmodium vivax contains genes that are expressed differently depending on the c) Plasmodium vivox 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 orgoni ) All of the explanations are equally plausible in explaining the morphological differences in ) None of the explanations shown exploin the morphologiaal differences in Plasmodium vivax.

Best explantion for homoplasy
A homoplasy is a character shared by a set of species but not present in their common ancester.
a best example is the evolution of the eye which has originated independently in many diffrent species. when this happens it is also called as convergent evolution.wings of insects ,birds and bats are all needed for flying , they are homopasious structures in the non evolutionary as well as evolutionary.
3.Answer is
The endosymbiotic theory was first praposed by Lynn Margulis. according t his hypothesis Mitocandria are the result of aerobic bacteria , chloroplast are the result of endocytosis of photosynthetic bacteria like cynobacteria so the answer is thylakoids in cynobacteria , endomembranes in protobacteria.
4.Answer is C
Plasmodium vivax contains several distinct genomes ,each aquired via secondary endosymbiosis.and contain genes that encode the proteins that make up each unique developements forms.
