(4) The animals belonging to these TWO PHYLA are triploblastic and they enclose a body cavity. (5) The coelomic cavity is filled with some substance and hence they are known as pseudo coelomate.

749.	Question : Give scientific reasons for the statements : On moving from the level of species towards the kingdom, gradually the similarities decreases and dissimilarities increases.
Answer» Solution :Species is the smallest and last unit of the classification. A species includes all organisms that are able to breed and perpetuate.Kingdom is the universal unit that includes all living organisms. From kingdom to Species, the living organisms are arranged orderwise on the basis of their SIMILARITIES : Phylum (for animals) / Division (for plants). Class, ORDER, Family, Genul, Species.Thus, moving from Species towards kingdom more and more groups get assembled. In classification, the living organisms of DIFFERENT groups SHOW diversity. Hence, on moving from the LEVEL of species towards the kingdom, gradually the similarities decreases and dissimilarities increases.
