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.

D. the diencephalon is where the thalamus is located

Hi. We just had a session with this same question is there any doubt left?

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.

Explanation:

The rate of cell division over time is calculated as an average for the entire meristem by dividing it with the total cell flux. Total cell flux may be characterized as the number of cells in the meristem.

Cell division may be defined as a type of biological process through which a parental cell divides into two or more daughter cells. There are two types of cell division are there:

According to the context of this question, the availability of the nutrient plays an active role in the process of cell division. It can increase the population of cells by doubling the rate of promoting growth and division of respective cells.

Therefore, the rate of cell division over time is calculated as an average for the entire meristem by dividing it with the total cell flux.

The statement that is true is as follows: the density of water is 1 gram per milliliter, so objects with a relative density greater than 1 gram per milliliter will sink (option C).

Density is the measure of the mass of matter contained by a unit volume. The density of a liquid substance is a determinant of whether the substance will float or sink in water.

Water is a liquid substance with a density of 1 gram per millilitres (1 g/mL). This suggests that any substance with greater density than that of water will sink while any substance with lesser density than water will float.

Density is a measure of how heavy something is compared to its size, hence, if an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

Therefore, according to this question, objects with a relative density greater than 1 gram per milliliter will sink.

To be considered as fit for evolution processes, a species must be able to adapt in its environment and with capacity to reproduce sucessfully. Ambrosia, for example, is an invasive species. It has the abillty to promote accelerated evolution due to its adaptibility to its environment. Zea mays is an excellent species for genetic analysis. Quercus also has evolutionary potential because of its physiological characteristics.

Micelium, which is formed by a number of filaments, has the main function of penetrating the substrate in search of food and nutrient. Moreover, it can suffer some modifications to form reproductive structures.

The correct option is: B. Nutrient absorption.

Explanation:

Kepler's First Law: The orbit of a planet around the Sun (or a satellite around a planet) is not a perfect circle. It is an ellipse—a “flattened” circle. The Sun (or the center of the planet) occupies one focus of the ellipse. A focus is one of the two internal points that help determine the shape of an ellipse. The distance from one focus to any point on the ellipse and then back to the second focus is always the same.

The law of ellipses suggests that the orbit of planets is not circular but ellipses

Therefore your answer would be; Ellipses

Answer:

The law of ellipses suggests that the orbit of planets is not circular but elliptical.

Explanation:

Kepler's first law (the law of ellipses) explains that the orbit of the planets around the sun is not in a circular but elliptical path.

And stimulus is a change in the organism or the environment that triggers a reaction, in this example, hunger causes the animal to hunt, so hunger would be the stimulus.

Answer:

All living things need to water to survive. This is because all living things are mostly made of water and since they lose water in different ways, they need to get more water to stay the same size. So if a plant does not get enough water, it will shrink. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive.

The cosmos is expanding at the quickest rate that astronomers have discovered. In actuality, nothing is known to move faster than the speed of light, which acts as a cosmic speed limit.

Answer:

Patagonia is the southern psrt of south america.

Answer: 1. The right answer is amphibian.

2.  The right answer is Mollusks.

Explanation:

1. Regenerating a limb is not possible in mammals, as in most vertebrates. But in amphibians such as the salamander yes!

This amphibian does it very well, capable of making tail, eye or snout too. For a very long time, scientists have been trying to understand this secret of the salamander, or that of the zebrafish, because the answer is scientifically interesting but also, of course, because we can hope to take advantage of it to imagine one day of medical treatment for injured members. Just over a year ago, an Australian team showed the role of macrophages, cells of the immune system.

2. Mollusks (Mollusca) are a branch of Lophotrochozoans animals. They are unsegmented animals, with bilateral symmetry sometimes altered. Their body usually consists of a head, a visceral mass, and a foot. The visceral mass is covered in whole or in part by a mantle, which secretes a calcareous shell. The nervous system includes a double periesophageal collar. The general cavity is more or less reduced to pericardium and nephridia.

We have to consider that the DNA is first transcribed into pre mRNA in the nucleus of the cell by the RNA polymerase. After this process, the non-coding fragments (introns) of the molecule are spliced by ribonucleoproteins (snRNP). Eventually, each end of the pre mRNA is modified, being a modified nucleotide named CAP joined to the 5' end, and a polyA (poly Adenine) tail at the 3' end before the now matured mRNA gets out of the nucleus to the cytoplasm.

At this point, the mRNA will be recognized by ribosomes, which will synthesize each group of three nucleotides (codons) into amino acids in a process called translation, by the action of tRNA, and finally joined into a new protein.

Note that A, P, and E are sites of the ribosomes, being A the position where first arrives the mRNA.

it is B C and D

Earth's distance and tilt affect the relative amounts of solar radiation regions receive.

Earth's distance and tilt affect the relative amounts of solar radiation regions receive. There are no options provided in the question, but this is the correct answer. The earth's orbit is not circular and the earth rotates in a tilted orbit. Whenever the south pole is tilted towards the sun, then the south pole will get more solar radiation than the north pole. The Earth absorbs most of the energy reaching its surface and a small fraction is reflected. In total, approximately 70% of the incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface.

As a protocol, the sample must first undergo primary biochemical tests, one of which is gram staining. And although this stain can help us to identify bacteria of the Clostridium genus, such as gram + sporulated bacilli, a more specific test would be the endospore stain, since the clostridium genus produces endospores that are also easy to isolate, since they are more resistant to temperature than the vegetative form (not sporulated) of the bacterium. An example would be the Schaeffer-Fulton stain.
