Question

Which of these is a hypothesized function for the intracardiac shunt seen in turtle hearts? The shunt allows for oxygen to move from the right lung to the left lung during exercise Reduction of blood flow to the lungs during diving to increase oxygen removal out of the blood Increasing blood pressure as blood flows through the pulmonary circuit Decreased flow of oxygenated blood to the brain during times of rest

Answer 1

1. Option C, because the ventricles are not completely subdivided into chambers thus mixing of oxygenated and deoxygenated blood takes place and thus increasing blood flow to lungs instead of rest of body.

3. Option C, sex determination depends on the incubation temperature, in research found that if Testudines eggs incubate in below 81.86F then it will develop into male.

4. Option C,

Amniotes are diapsides, turles also evolved as diapsides means two temporal fenestration. Some times earlier fossil of turles do not have two fenestration means placed as reptiles they are anapsids.
