Explanation
Solution
Sexual cycle. The causative agent of malaria is P.vivax. It has two phases: the sexual phase takes place in the female Anopheles mosquitoes and the asexual phase takes place in the RBC of the host. The mosquitoes inject sporozoites that will enter the bloodstream of humans. The sporozoites travel to the cells of the liver and multiply asexually. The cells then ruptures so that the merozoites are released into the bloodstream.
