Consider the generalized cladogram of fish. a fossilized fish is found that has jaws but no true bones. where does this fossil belong on the cladogram?

In the cladogram, the fossil belongs to D.

A cladogram belongs to the branching tree-like diagram used to demonstrate an evolutionary association between the species. A point of divergence exhibit two branching lines of descendence, suggesting an evolutionary divergence from a common ancestor.

As these fossils exhibit jaws but do not possess true bones it can be presumed that they originated 395 million years ago in the mid of the Devonian period.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

not sure if this what   you'r looking for would be percent composition
