Enzymes perform their functions within a specific temperature and pH range (which is specific for each enzyme in particular). In turn, within this range, there is a specific value at which they act in the most efficient way possible, which does not mean that they cannot on other values in the range. However, outside the limits of the range, the internal characteristic of enzymes can be affected and cause their denaturation, thus losing their capacity of action.

The image points to a vessel that comes from the bottom of the heart and reaches its top to attach to it on the top. It is called aorta.

Explanation:

The 3 postulates of the Cell Theory are:

-Every living being is composed of cells, therefore they are the minimal functional unit of life, in their different levels of structural complexity. One single

cell is enough to make up an organism, but also multiple cells can organize in colonies or in a single organism, diversifying their functions and having a margin of independence quite elevated as a whole.

-All of the vital functions of living organisms have a place inside the cell, through biochemical processes and are controlled by substances that the cell secrete. Each cell operates as a unique open system, that exchanges matter, and energy with its environment in a controlled way. Moreover, in each cell of an organism are present the same vital functions that are in the organism itself, that is birth, growth, reproduction, and death.

-Every existing cell comes from a previous cell, by cell division, or by formation from stem cells.

A serum amylase is diluted 1/100 with a result of 45.0 U/L. The patient's actual amylase result is 4500 U/L.

Serum- Serum generally refers to the transparent fraction of any biological fluid, whether it comes from an animal or even a plant. For instance, the fluid released by serous glands is known as mammal serous (or serosal) fluid. The serum in blood is a clear, pale yellow liquid that is separated from of the blood and thus is free of blood cells & clotting components.

Amylase- The primary job of amylases is to hydrolyze all glycosidic linkages in molecules of starch, turning them to simple sugars. The three primary kinds of amylase enzymes—alpha, beta, and gamma—each affect the carbohydrate molecule in a different way.

In developing countries with high population rates, people generally thrive at a trophic level of 2.2.

Trophic levels are the positions that feed in a food chain or web. The population size diminishes as you move up the trophic levels of an environment.

Numerous consumers consume food at various trophic levels. When people eat plants like vegetables, they are the primary consumers. When they eat cows, they are incidental consumers. When they eat fillets, they are secondary consumers.

Higher trophic levels typically have fewer creatures since there is less energy there. At higher trophic levels, organisms are often greater in size, but because there are fewer of them, there is less biomass produced. The total mass of all trophic-level creatures is known as biomass.
