Vedclass · Answer

(A) $1$. Amphibians typically have moist,glandular skin without an exoskeleton of scales. Scales are characteristic of reptiles (Reptilia) and fish (Pisces).$2$. Mammals possess an exoskeleton derived from the epidermis,which includes structures like nails,hooves,claws,and hair.$3$. Aves (birds) have an exoskeleton consisting of feathers and epidermal scales on their legs.$4$. Echinoderms possess an endoskeleton made of calcareous ossicles ($CaCO_3$ plates),not an exoskeleton. Therefore,option $A$ is the mismatched pair.
