Evolutionary Tree / Sorting Activity Create your own tree-branching model to organize the beetles based on ages and similarities in structures.
You can do this activity in different ways - depending on your resources and what helps you understand:
1. If you have a printer, you could print this document and cut out and arrange the beetles.
2. If you don't have a printer, write the letters on a piece of paper, cut them out and arrange them.
3. Or, just write the letters on a piece of paper in an organized tree-branching model.
A, B and C are modern-day beetles, while the others are fossils. The numbers in parentheses tell how many
millions of years old the fossils are, based on absolute dating.

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.
