Tropical ocean waters are more saline than colder waters because tropical waters

get salt from currents

get more sediments

have more fish

evaporate more rapidly

evaporate more rapidly

Explanation:

the faster the water evaporates the more salt it leaves behind.

The reason for more salinity of Tropical Ocean when compared to cold water is rapid evaporation.  

The rate of evaporation is very high in case of Tropical Ocean than the cold water. Tropical seas receive more solar radiation consistently. The water present in tropical seas is warm, around 27°C (80.6ºF).

Due to this reason, the rate of evaporation is very high in which the salt at the end of evaporation remains in the ocean and leads to high salinity of the tropical ocean.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

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.
