Suppose that individuals of a particular genetic strain of drosophila melanogaster reproduce at an earlier age than do other strains of this species. as a consequence, they tend to die sooner. which maxim does this phenomenon exemplify?

there is no such thing as a free lunch

Explanation:

The maxim "There ain't no such thing as a free lunch" also known as "there is no such thing as a free lunch" (TINSTAAFL), indicates the cost of decision-making and it's aftermath.

In this senerio, a particular genetic strain of Drosophila melanogaster reproduce at an earlier age than do other strains of this species at the expense of its lifecycle as this will cause a shortage of its lifecycle which is a negative aftermath compared to other strains that do not reproduce early.

the answer is c) abandoned properties that are contaminated with hazardous materials.

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.
