A graph of predicted species diversity and extinction rates on different islands is shown here. Assume that a group of island forms off of the mainland from volcanic eruptions, creating islands of bare rock. Which of these describes the processes that provide for the
greatest species diversity after an island forms?

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.  

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
