Apopulation of ducks lives in an area that floods many times each year. some of the ducks are better at finding food on dry land, while other ducks are better at finding food in wet, muddy areas. eventually, the land around the lake permanently changes from dry soil to wet, marshy mud.
how will this change to the land most likely affect the duck population?
the population will remain stable because the ducks will not be affected by this kind of change.
the population will eventually balance out so that there are equal numbers of both types of ducks.
the population will evolve so that most ducks survive no matter how they find food.
the population will evolve so that most ducks are better at finding food in wet, muddy areas.

The population will evolve so that most ducks are better at finding food in wet, muddy areas.

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.
