Answer:

The correct answer is: place the pulse oximeter in the baby's toe.

Explanation:

  • A pulse oximeter is a non-invasive medical device.
  • It is used to determine the concentration of oxygen-linked haemoglobin flowing in through the peripheral arterial blood.
  • It is generally used in those parts of the body where the skin is thin, like the finger tip of hand, toe tip or the ear lobe.
  • The difference in the absorbance of infrared light by the haemoglobin molecules linked to oxygen and the haemoglobin molecules not linked to oxygen is used to determine the concentration of oxygen in the peripheral arterial blood.
  • As the child has a difficulty in breathing so, it is obvious the amount of oxygen that all its body cells receive is far less than the amount of oxygen needed by them.

andre [41]

<u>Complete Question:</u>

Which statements describe proteins? Check all that apply.

A.) Proteins are created from the code in DNA.

B.) Proteins are synthesized in the nucleus of a cell.

C.) DNA and RNA are proteins.

D.) Amino acids are the building blocks of proteins.

E.) Proteins affect the structures and functions of living things.

F.) The shape and the function of a protein are not related.

<u>Correct Option:</u>

The statements which describe proteins are as follows:

A.) Proteins are created from the code in DNA.

D.) Amino acids are the building blocks of proteins.

E.) Proteins affect the structures and functions of living things.

<u>Explanation:</u>

Transcription is the method of RNA molecule creation from DNA. The translation is the mechanism by which the protein material is produced from the RNA molecule. Originally, protein forming data is contained in the DNA in the context of nucleotide code. The mechanism of translation happens in the cytoplasm and not at the nucleus.

DNA and RNA contain nucleotides and not proteins. Proteins are the alpha amino acid polymers, which serve as the building block of the protein. An individual's phenotype relies on the composition of the protein, and protein determines the composition and phenotypic expression in living organisms. 3D structure of proteins and their work are realized with one another.
