The figure shows four animals (a), (b), (c) and (d). Select the correct answer with respect to a common characetrsites of two of these animals (a)
1 (c) and (d) have a true coelom
2 (a) and (d) respire mainly through body wal
3 (b) and (c) show radial symmetry
4 (a) and (b) have cnidoblasts for self defence
Explanation:
A True coelom, which refers to a body cavity that is completely lined by mesoderm is found in the mollusca, annelids, arthropods, echinoderms \& chordates. - In all advance invertebrate phyla have a true coelom. - The formation of coelom splitting of mesoderm. - This kind of coelom called shizocoelomates. Octopus- Belong from phylum mollusca and order Octopoda. Scorpion- It is predatory organism (Arthropod) class Arachnid. - The coelom forms by out pocketing of the primitive gut. - It is thus called enterocoelomates.

Coelom derived from blastocoel is known as :
1 haemocoel
2 enterocoelom
3 pseudocoelom
4 schizocoel
Explanation:
C A pseudocoelomate is also known as a blastocoelomate. Some animal, the body cavity is not lined by mesoderm, instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Such a body cavity is called pseudocoelom and the animal possessing them are called pseudocoelomates. - A pseudocoelomate is often a small animal, which relies mostly on diffusion to distribute oxygen and nutrients to its cells.

Which of the following animals has a true coelom?
1 Ascaris
2 Pheretima
3 Sycon
4 Taenia solium
Explanation:
B The body cavity lined by mesoderm is called coelom. Animal having coelom are called coelomates e.g. Annelids, Echinoderms and Chordates. Pheretima belongs to phylum Annelida. These are nocturnal in habit and live in damp, moist, humus rich soil of lawns, gardens etc. Body is long, narrow and cylindrical and colour in brown. Body is divided into 100-140 segments called metameres. - Pheretima has true coelom (schizocoel). The coelom is filled with milky white alkaline coelomic fluid.

Book lungs are the respiratory organs in:
1 Protozoans
2 Cnidarians
3 Arthropods
4 Amphibians
Explanation:
C Book lungs are a type of respiratory organ in arachnids such as spiders, and scorpions. - They are known as book lungs because of their stacked-plate appearance resembling closed pages of a book. - 4 pairs of book lungs are found in scorpions and two pairs are found in spiders. - The book lungs are located inside the animals of class arachnid Arthropoda. - It is filled with haemolymph that carries oxygen.
