The heterokaryotic phase of a fungal life cycle is the heterokaryotic phase of a fungal life cycle is a stage in which hyphae contain two, genetically different, haploid nuclei. a triploid stage formed by the fusion of a diploid nucleus with the haploid nucleus of a compatible hypha. a stage in which the hyphae contain only one type of haploid nucleus. a stage in which hyphae contain two, genetically different, diploid nuclei.

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.
