Vedclass · Answer

(C) $1$. In $Reptiles$,the heart is generally three-chambered (two atria and one partially divided ventricle),except in crocodiles which have a four-chambered heart. Thus,this statement is not universally true for all reptiles.$2$. In $Amphibians$,the endoskeleton is mostly bony,not pneumatic. Pneumatic bones are a characteristic feature of $Aves$ (birds).$3$. In $Bony 	ext{ } fishes$ $(Osteichthyes)$,the mouth is generally terminal,whereas in $Cartilaginous 	ext{ } fishes$ $(Chondrichthyes)$,the mouth is ventral. This statement is correct.$4$. In $Molluscs$,locomotion occurs via a muscular foot,not tube feet. Tube feet are a characteristic feature of $Echinoderms$.

Characteristic	Cyclostomata	Chondrichthyes	Osteichthyes
$(i)$ Habitat	Marine	Marine	Marine,Fresh Water
(ii) Mouth	Sucking mouth	Ventral mouth	Terminal mouth
(iii) Gill Slits	$6-15$ Pairs	$5-7$ Pairs	$4$ Pairs
(iv) Scales	Absent	Placoid	Cycloid/Ctenoid
$(v)$ Fins	Unpaired	Paired	Paired
