One animal that does not perform locomotion is
1 Sycon
2 Nereis
3 Sepia
4 Euglena
Explanation:
A Sycon is a sponges that belong to phylum porifera. Sponges are sessile as they are attached to a substratum. Hence, Sycon does not perform locomotion - In Nereis locomotary organ is parapodia. - In Sepia (cuttlefish) locomotary organ is fins. - In Euglena locomotary organ is flagella.

Members of phylum Porifera are
1 exclusively marine animals
2 exclusively fresh water animals
3 mostly fresh water animals but few are marine animals
4 mostly marine animals but few are fresh water animals
Explanation:
D Sponges are the members of phylum porifera. They are generally marine and asymmetrical animals but few are freshwater animals. They show cellular level of body organization. Spicules or sponging fibres make up the skeleton of sponges. It provides them structural support.

Which one of the following statements about all the four of Spongilla, Leech, Dolphin and Penguin is correct -
1 Penguin is homoeothermic while the remaining three are poikilothermic
2 Leech is fresh water form while all othersare
3 Spongilla has special collared cells called choanocytes, not found in the remaining three
4 All are bilaterally symmetrical
Explanation:
C Spongilla belongs to phylum porifera, in which the characteristic cells are choanocytes, these are absent in leech, dolphin and penguin. These collared cells called choanocytes, are not found in remaining three species. These collared cells which have flagellated structures aid in food capture and movement. - Dolphin and Penguin are a homeothermic while other two are poikilothermic. Spongilla and leech are the freshwater and penguin and dolphin are marine water animal. - Spongilla is asymmetrical while other three are bilaterally symmetrical.

Which one of the following statements is incorrect?
1 Insects have one pair of antenna
2 Millipedes possess two pairs of appendages in each segment of the body
3 Prawns have two pairs of antenna
4 Animals belonging to the phylum-Porifera have nematocyst
Explanation:
D Nematocyst : The nematocyst present in coelenterate are exclusive stinging apparatus of the cnidocytes. It is a distinguishing feature of the phylum coelenterate. - It helps to capture the prey and serve for adhesion, offence and defense. It also helps in locomotion and food capture.

Which of the following characteristic features always holds true for the corresponding group of animals
1 Feature - Reptilia
2 Feature - Chondrichthyes
3 Feature - Mammalia
4 Feature - Chordata
Explanation:
B Chondrichthyes contains the cartilaginous fishes which have endoskeletons composed of cartilage. - Reptilia have 3-chambered heart, except crocodiles, which have three and half chambered heart. - All mammalia are viviparous except monotremes, viviparous give birth to young ones and the development of offspring is inside the mother body. - Chordata possess a mouth with an upper and a lower jaw, but jawless fish don't have any jaw.
