Prior to the publication of charles darwin's book, on the origin of species, what was the prevailing public consensus regarding species evolution?

The prevailing public consensus regarding species evolution was that species were permanent and unchanging, prior to the publication of Charles Darwin's book, On the Origin of Species,

On the Origin of Species, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. 

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully

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.
