How are Xylem and Phloem different?
Describe the path of water through the plant - this is called Transpiration.
Where should you give a plant water? Explain your answer. What happens to the plant if we don’t give it water?
How does Xylem relate to the rings of a tree? How can we tell the age of a tree by its rings?
Why are some plants carnivorous (why do they eat insects/other animals)? Give an example of a carnivorous plant, and explain how it “eats”.

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.
