The equilibrium theory of island biogeography has been used to make predictions about how island size and distance as well as species richness affect immigration rates, extinction rates, and turnover rates. which of the following predictions does not follow from the theory of island biogeography? (note: the phrase "all else being equal" applies to each option.)
a. immigration rates increase as an island's distance to mainland decreases.
b. extinction rates increase as the number of species on an island increases.
c. extinction rates decrease as the size of an island decreases.
d. turnover rates decrease as the size of an island increases.

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.  

whats the drop down answers ?
