There are several properties of water that make earth a suitable environment for life, including water's high boiling point and high heat capacity. which best explains why this characteristic of water is important for marine life?
a.) it allows water to remain in its liquid form even at relatively high temperatures.
b.) it allows water to vaporize easily, powering the water cycle.
c.) it allows water to be denser, making it easy for living organisms to move through.
d.) it allows water to resist freezing and thawing cycles.

D.) It allows water to resist freezing and thawing cycles.

The ability of the water molecule to absorb and retain heat is called as heat capacity of water, because of this property the temperature of water remains the same for long, irrespective of the external environment. It allows water to resist freezing and thawing cycles because water molecules will resist change in it's temperature. This temperature regulation will prevent instant heating and cooling, hence, will provide suitable environment for the survival of marine organisms.  

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

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.
