Answer 1

Answer:

option d is correct bro/sis

Answer 2

Question:

Ratio of the body surface to the body size is

less in

(A) Warm blood animals living in colder

regions.

(B) Warm blood animals living in warmer

region.

(C)Cold blooded animals living in colder

regions.

(D) All vertebrates living in warmer

regions​.

Concept:

Allen's rule - Accordingly to Allen's rule formulated by Joel Asaph Allen (1877), animals living in cold regions have thicker limbs and bodily appendages than the animals living to warm regions.The rule states that the body surface-area-to-volume ratio for homeothermic animals varies according to the average temperature of their habitat to which they are adapted.

Answer:

(D) All vertebrates living in warmer

regions​.

Explanation:

Accordinly Allen,s rule - animals living in warmer region have less body size than animals living in colder region.

Also Gloger's rules states that animals of colder region possess thick coat of hair, scales, feathers and subcutaneous fat. That's why their body size is normally bigger.

Bergmann's rule states that warm blooded animals of colder regions are of larger size as compared to those who live in warmer regions.

So, option - (D) All vertebrates living in warmer

regions​ is the right answer.
