Explanation

Plasmodium falciparum is a protozoan parasite, one of the species of Plasmodium that causes malaria in humans. Being digenetic, its life cycle is complete in two hosts-man and mosquito. Its sexual cycle is completed in the female Anopheles mosquito and infective individuals called sporozoites are formed, Which are transmitted to humans with the bite of infected female Anopheles. The asexual cycle is passed in man in two phases. Malaria caused by P. falciparum (also known as aestivoautumnal, malignant tertian, or pernicious malaria) is the most dangerous form of malaria, with the highest rate of complication and mortality. In this case, the fever cycle is of 48 hours and is often fatal to the patient as it affects the brain. The scientific name of the common house lizard is Hemidactylus whereas Musca domestica is the scientific name of the common housefly. The scientific name of the Indian tiger is Panthera tigris. The full name of E. coli is Escherichia coli.

About Biodiversity and Variety of Life

Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
