In an amphibian blood entering the right atrium shows higher levels of oxygenation than that in left atrium when :
A.It is hyperactivated
B.it is hibernating
C.it is submerged
D.it is in the terrestrial habitat
I think it should be C.
I think the answer should be C because when it is submerged, cutaneous respiration takes place and hence right atrium receives more oxygenated blood.
