<span>It is believed that the coelacanths and lungfish (lobed fin fishes) represent a crucial link between other fishes and tetrapods. The major feature to support the hypothesis is : </span>Their fins have skeletal and muscular structures similar to amphibian limbs.
1.) Evaporation Rate
evaporation removes water amd increases salinity
2.) Precipitation Rate
increases amount of water, contributing to overall salinty
3.) Temperature
increase of temperature= decrease of density
4.) Freshwater
amount of freshwater (added) = less salt
Smoke is the correct answer. good luck
