<span>Pulmonary circulation is the movement of blood starting from
the heart, where deoxygenated, or carbon dioxide-filled, blood leaves from the
right ventricle and through the pulmonary valve, then into the left and right
pulmonary arteries and arrives at the lungs. During the process of respiration,
the carbon dioxide is released and oxygen is added to the blood. Then, the
pulmonary veins carry the oxygenated blood back to the heart, entering into the
left atrium, completing the circulation. The correct answer is B, pulmonary.</span>
The correct answer here would be mole, as this is the unit of
measurement used to determine the amount of a substance being used. This
particular measurement is usually used during chemistry experiments as
it determines how many representative particles there are in any one
amount of substance.

Answer:
The correct answer is - a. NADH
Explanation:
The Krebs cycle is a set of chemical reactions that takes place to generate energy from nutrients such as carbohydrates, fats, and proteins converting to carbon dioxide. by oxidation of acetate.
In the Krebs cycle, each molecule of carbon generates 3 molecules of NADH, one molecule of ATP and 2 molecules of FADH2 in each cycle. Thus, the greatest numbers during one turn of the Krebs cycle is NADH.
Even though there are no choices given in this particular question, the principle of osmosis is very easy to understand.
When we talk about osmosis, we are referring to the movement of water from a low concentration to a higher concentration. This is different from diffusion, which talks specifically about the movement of <em>solutes</em> in the solution (from a higher concentration to a lower concentration.)
When an RBC is placed inside a <em>hypertonic </em>solution, the water inside the RBC will go out thereby shrinking the RBC.
Inside an <em>isotonic</em> solution, the RBC will remain the same because the concentrations are equal.
Inside a <em>hypotonic</em> solution, the RBC will lyse or explode because water will move from the solution going inside the RBC.
