Answer:
volume of 2% saline (V₁) = 0.25ml
volume of water = 4.75ml
Explanation:
The requirement in the question is to obtain 0.1% of NaCl from 2% NaCl, and the process is dilution. The general dilution equation is guven by:
C₁V₁ = C₂V₂
where:
C₁ = initial concentration = 2%
V₁ = initial volume = ?
C₂ = final concentration = 0.1%
V₂ = final volume = 5ml
C₁V₁ = C₂V₂
calculating for V₁
∴ V₁ = (C₂V₂) ÷ C₁
= (0.1% × 5) ÷ 2%
V₁ = 0.25ml
Now, let us calculate the volume of water needed:
V₁ + Volume of water = V₂ (volume of 0.1% NaCl)
0.25 + volume of water = 5
volume of water = 5 - 0.25
volume of water = 4.75ml

Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, <u>the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body</u>.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.
