The answer is septum.
Frog hearts have 3 chambers - one ventricle and two atria. The left atrium receives oxygenated blood, and the right atrium receives deoxygenated blood and they both empty into the ventricle. Since there is only one ventricle, oxygenated and deoxygenated blood will mix. If there would be a septum in the ventricle, similar to those in lizards, less mixing will occur. Anyway, in frog's ventricle, there is a ventricular fold that prevents complete mixing of oxygenated and deoxygenated blood.
Quantitative data are data which are measured through direct sources of measurements; this means that we can observe them directly and measure them directly with the tools we're using. An example of this would be measuring the length of a football stadium with a measuring tape. Another would be measuring weight with a scale.

The chemical equilibrium is used to deal with the extend reaction that occurs with ATP as just a high energy molecule
activation energy is the energy requierd to overcome this reaction.
So the answer would be. D. Metabolism
Metabolism invades the making of molecules and the breaking down of molecules
