What is magma?
solid rock with a fine texture
cooled rock with large crystals
molten rock below earth's surface
flowing rock above earth's surface

C. molten rock below the earth's surface

Explanation: Magma is called magma because that is the name of lava before it comes out of the ground.

Molten rock below Earth's surface.

Magma is actually melted rock that is hot enough to flow or a hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

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.
