Answer:
The separate systemic and the pulmonary conditions all evolve in the species that are having the high pressure circulatory system required for rapid movement of blood because if pulmonary was under pressure as high as that of the system circulation.
Explanation:
Here, it is given that the separate systemic and the pulmonary circulations evolve in the species.
And those species have the high pressure circulatory system for blood movement rapidly because if the pulmonary was under pressure as high as that of systemic circulation.
Also the fluid amount that will flow would be forced out of the cappilaries in the lungs.
Now, there is a conflict between the thin surface required for efficient exchange of gases.
Also, the thick blood vessels are required to withstand the high blood pressures.
running water can be used as an energy source to produce hydroelectric power.

Answer:
The middle carbon atom of pyruvate in the TCA cycle becomes the carboxyl carbon of acetate and hence the newly added (upper) carboxyl group in citrate
Explanation:
Before entering the TCA cycle, pyruvate is converted into Acetyl-CoA by oxidative decarboxylation of pyruvate. 1st two carbons of glucose to be fully oxidized. This reaction is catalyzed by Pyruvate dehydrogenase.
The middle carbon atom of the pyruvate in the TCA cycle becomes the carboxyl carbon of the acetate as the carboxyl group is removed from the pyruvate , releasing CO2. NAD is reduced to NADH. Acetyl group is transferred to coenzyme-A , resulting in acetyl coA
