What are important differences in the overall metabolic needs of a fish and a turtle and the ability of their circulatory systems to meet those needs? check all that apply?

Respuesta :

The most appropriate is that;Turtles have a double circulatory system whereas fish have a single circuit system. 
Amphibians such as turtle have three chambered heart that has two atria and one ventricle rather than two chambered heart of a fish. The two atria receive blood from the two different circuits (lungs and the systems), and therefore they are described as having double circulation while the fish have single circulation.
