Read the following scene:
rainwater flows quickly over a grassland, filling lazy streams and soaking deeply into the ground. days later, nearby vegetation grows quickly and the grassland seems to come to life.
conclude that the above scene best represents which of the following two loops?

a) precipitation loop and evapotranspiration loop
b) surface runoff loop and groundwater loop
c) precipitation loop and groundwater loop
d) surface runoff loop and evapotranspiration loop

Option (B)

Explanation:

The surface runoff usually refers to the flowing of water along an inclined surface over a large or small distance. These waters are accumulated in the land areas, rivers, and streams.

On the other hand, groundwater refers to the water that is present below the surface of the earth. When water accumulates over the land areas that are porous and permeable, it allows the water to percolate down into the deeper zone and eventually becomes groundwater.

In the given condition, the flowing of the water over the grassland areas and adding to the streams refers to the surface runoff loop. And the percolation of water into the deeper root zone and enriching the vegetation refers to the groundwater loop.

Thus, the correct answer is option (B).

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.
