Experimental prediction: Predicting longer-term changes in beak size

Although the Grants did not begin their study of the finch population until the early 1970s, there is enough information to assume that prior to the 1977 drought, rainfall was sufficient and the finch population thrived by eating abundant, smaller seeds. It is also assumed that during that period of time, no other environmental changes affected the finch population.

After 1977, rainfall amounts returned to their normal pre-drought levels for the next 25 years. Smaller seeds were once again abundant on the island.

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.  

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
