Aprotein is composed of a long chain of monomers called?

Answer;

Amino acids

Explanation;

-Amino acids are the monomers used to build the chains that eventually become proteins. There are approximately 20 - 22 different common amino acids. They are joined together in long chains by chemical reactions that eliminate water and create joins between them called peptide bonds.

-When joining two amino acids together cells carry out a chemical reaction between the amine group of one amino acid and the carboxylic acid group of the second amino acid. A molecule of water is eliminated during this reaction which is called a condensation reaction or a dehydration synthesis.

-Two amino acids linked together in his way is called a dipeptide and a long chain of amino acids is called a polypeptide.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
