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.

To be connected with pet owners.

Explanation:

For doing this job, i have to be connected with the people having pets in their houses because with this interaction I provide all information about genetic disorders that their pet can gain. I will attend group discussion with these people in order to avoid threats of genetic disorder to their pets. With this information, these people are able to diagnose any genetic disorder symptoms in their pets and if we knew on time this genetic disorder can be eliminated from their pets and their health should be maintained.
