Put the stages of fossil fuel formation in their correct order .
* natural gas is forced into crevices or
sedimentary rock pores.
•oxygen is used up or expelled.
•amount of heat dictates physical state of
fuel
•material is buried in sediment and silt.
•heat and pressure are applied.
•organic material decomposes

Explanation:

•Material is buried in sediment and silt.

•Organic material decomposes

.Oxygen is used up or expelled.

•Heat and pressure are applied.

•Amount of heat dictates physical state of  fuel

* Natural gas is forced into crevices or  sedimentary rock pores.

For fossil fuels to form, the correct natural processes must play out in a geologic formation. Fossil fuels are sourced from materials that becomes buried in sediments usually in a sedimentary basin. In the basin, the organic material decomposes in the presence of oxygen. With increasing compaction and burial, the oxic environmental cuts off and the decomposition ceases. As burial continues, heat and pressure is applied to the formation and natural gas is produced. The amount of heat dictates the physical state of the fuel that would be produced be it solid, liquid or gas. The fuel is then forced into reservoir rocks through traps.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

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.
