Q. What are the difficulties that you would face in the classification of animals, if common fundamental features are not taken into account?
Answer: The purpose of classification of animals is to trace the common features among different species and group them based on the common fundamental features rather than considering every feature of an organism since it does not serve the objective of classification. Every individual will have to be studied independently, and the correlation among species cannot be identified, and hence, evolutionary significance at an individual level cannot be traced. The classification of animals based on fundamental features also helps in the binomial nomenclature.
Q. How important is the presence of air bladder in Pisces?
Answer: Air bladder in bony fishes ( Class – Osteichthyes), allow them to balance themselves in water without sinking, hence maintaining the buoyancy. It also allows the fish to move upwards, downwards or stay in the current.
Q. Segmentation in the body is first observed in which of the following:
(a) Platyhelminthes (b) Aschelminthes (c) Annelida (d) Arthropoda
Answer: (c) Annelida
The body of these organisms is marked into segments or metameres, hence the name Annelida, where annulus means little rings.
