You have an octapeptide that consists of ala, arg, met, gly, pro, cys and ile. The octapeptide was first treated with pepsin, which resulted in two tetrapeptides, P1 and P2.
P1 was treated with aminopeptidase which resulted in A1 (a single amino acid) and A2 (a tripeptide).
A1 turns yellow in the presence of ninhydrin.
A2 was treated with trypsin which resulted in T1 (a single amino acid) and T2 (a dipeptide).
T2 was treated with carboxypeptidase which released gly and met.
P2 was treated with elastase which resulted in 2 dipeptides, E1 and E2.
E1 was treated with aminopeptidase which released ala and another amino acid.
E2 was treated with carboxypeptidase which released an amino acid and ala.
Based on this information, and your knowledge that may date back to BIOL 190, determine the
amino acid sequence of the octapeptidelind record it as you previously have recorded peptide
sequences using lower case and hyphens in standard peptide equencing format.

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.  

b. climate change will cause an increase in biodiversity of all ecosystems.
