Which structure would be most beneficial for a plant in tundra biome

The structure would be most advantageous for a plant in tundra biome should be  superficial roots that do not reach the frozen soil

The tundra is recognized for its shortage of trees. The short summer period results in a compressed growing season, which makes it challenging for trees to grow longer. The cold temperature of the permafrost also introduces slower decomposition, which limits the number of nutrients being recycled through the atmosphere.

well the answer is 2!

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.
