When people travel to another area and successfully mate with people in the
population there, a transfer of genes occurs between the populations even though the
traveler returns home. For example, when U. S. soldiers had children in Southeast Asia
with Vietnamese women during the war there in the 1960's and early 1970's, they
altered the gene pool frequencies of the Vietnamese population.
This is an example of..
bottle neck
natural selection
coevolution
gene flow

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.  

they kick it to the curb.

that current was nasty.
