Answer:

a contaminant concentration

Explanation:

The concentration of the ingested contaminant determines the toxicity potential of the contaminant. All chemicals are acute toxicants if they are ingested in large amounts. The target organs and mechanism of action of these toxicants may vary but their potential to become toxic depends entirely on their absorption concentration. For example, Ethanol causes CNS depression but may lead to Liver cirrhosis if the concentration in body is very high.

Macronutrients (needed in relatively large amounts) are often listed as CHONPS. What does each of these letters indicate, and wh
Pavel [41]

Answer:

CHONPS stands for

C: carbon

H: hidrogen

O: oxygen

N: nitrogen

P: phosphorous

S: sulfur

They are needed by the cell because each of these elements combines to form the molecules that our body needs to exist since they make the biomolecules, which are amino acids, lipids, carbohydrates, nucleic acids, proteins, and vitamins.

Explanation:

CHONPS are the initials for the most abundant elements in our body (Carbon, hydrogen, nitrogen, phosphorous, and sulfur). CHOMPS form the biomolecules of our body. That is to say, they make lipids, carbohydrates, proteins, amino acids, and nucleic acids, so we need nutrients that contain the CHONPS elements, in large amounts, for our cells to function and the structure of our body.

Doctors have injected a patient with a freely filtered substance that can be neither reabsorbed nor secreted. What is an example
julsineya [31]

Inulin is an illustration of material of this type that cannot be reabsorbed or secreted.

How does inulin avoid being both reabsorbed and secreted?

  • Due to its special characteristics, inulin is the only chemical whose clearance is precisely equal to the glomerular filtration rate (GFR).
  • Although inulin is readily passed across the glomerular capillaries, neither is absorbed into the body nor released after filtering.
  • As a result, the volume of inulin filtered and excreted will be the same. Because of these factors, inulin is referred to as a glomerular marker.
  • The clearance ratio, which is the comparison between the clearance of any drug (x) and the clearance of inulin, is used to express this comparison. Thus,

                           Clearance ratio = C_{X} / C_{inulin}

Therefore it can be concluded that inulin cannot be released or reabsorbed after being injected into a patient.

for a patient with a new onset of Meniere disease, which meal choice indicates understanding of dietary modifications provides b
slavikrds [6]

For a patient with a new onset of Meniere disease the dietary modification icludes low salt diet and reduction of alcohol and caffeine daily intake.

An idiopathic inner ear ailment called Meniere's disease (MD) is characterised by tinnitus, fluctuating sensorineural hearing loss (SNHL) and spontaneous recurrent vertigo. Dietary changes, such as a low-salt diet and a daily intake reduction of alcohol and caffeine, are frequently used as the first line of treatment.

It is thought that a low salt consumption can aid to reduce endolymphatic pressure. Increased water and alcohol consumption enhances hearing and reduces the age at which Meniere's illness first manifests.
