Studies of populations that reveal correlations between dietary habits and disease incidence are epidemiological studies.
Creatinine is a by-product of muscular metabolism. In the natural and normal scheme of things, this substance or waste product can be eliminated from the body. A high-serum creatinine level may cause kidney damage. In relation to the above question as to how high can creatinine levels go before death, it must be noted that kidneys have strong compensatory ability and by that as long as its still 50 percent functional, creatinine level won't be that high. Which leads us to a conclusion that, the lesser the kidney function level is, the higher the creatinine level.
On the other hand for the blood urea nitrogen (BUN) is the most stable blood constituent following death as it reaches antemortem (before death) levels and even after moderate decomposition.
Therefore, as long as the kidneys are functional, regardless of other factors such as the patient's condition/ diagnosis, these blood constituents are nearly normal.

Answer: germ theory
Explanation: Germ theory of disease is a theory in biology. It says that small organisms (called germs), also known as microbes, cause diseases. Most, but not all diseases are infectious diseases. The germ theory states that small organisms cause a reaction in the body of those who are infected. The body's reaction to infection is called a disease.

Answer:
Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins).
Explanation:
Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins). The essential capacity of capillaries is the trading of materials between the blood and tissue cells.
Blood vessels a cylindrical organization all through the body that permits blood to spill out of the heart to each body cell and afterward back to the heart. The three kinds of veins are corridors, vessels, and veins. Each vein comprises of a layered divider encompassing a focal blood-containing space, or lumen.
