Question

Which of the following are correctly matched with respect to their taxonomic classification?
(A)Centipede, Millipede, Spider, Scorpion- Insecta
(B)Housefly, Butterfly, Tsetse fly, Silverfish- Insecta
(C)Spiny anteater, Sea urchin, Sea cucumber- Echinodermata
(D)Flying fish, Cuttlefish, Silverfish- Pisces

Answer 1

Every taxonomic group has certain characteristics that represent taxa and are not seen in other taxonomic groups. These characters are what make the organisms distinguishable from other organisms of different taxa.

Complete answer:
From the above option, the correct matching of organisms with their taxonomic classification is Housefly, Butterfly, Tsetse flies, and silverfish- Insecta. All these organisms are members of the class Insecta and possess 3 pairs of legs, two pairs of wings, and two antennae with a segmented body.
In option A, centipede belongs to the class Chilopoda and millipede belongs to Diplopoda. Spider and scorpion are members of class Arachnida.
In option C, Spiny anteater belongs to class mammals, sea urchins to Echinoidea and sea cucumber is a member of class Holothuroidea.
In option D, Flying fish is a member of class Actinopterygii whereas cuttlefish and silverfish belong to class Cephalopod and Insecta respectively.

So, the correct answer is "Housefly, Butterfly, Tsetse fly, Silverfish- Insecta".

Note: Insecta is the largest group of organisms with phylum Arthropoda and their characteristics show 3 pairs of the leg attached to a segmented body. They have a chitinous skeleton and the body is divided into three parts- head, thorax, and abdomen. They also possess a pair of antennas in the head region. Insects are found in almost all environments and it is the most diverse group of animals including more than a million described species till now and they consist of more than half of all known living organisms. Housefly, butterfly, tsetse fly, and silverfish all have the characteristics of Insecta, therefore, are included in this taxa.
