Freshwater fish have more salt in their bodies than the water around them does. So the water goes directly into their bodies through their gills(鱼鳃). These fish don’t really have to drink water through their mouths like we do.Saltwater fish, on the other hand, have less salt in their...
Why is seawater a better conductor of electricity than water from a freshwater lake? Why do non-polar substances not dissolve in water? Why does the addition of ice water in the synthesis of 4-bromo-2-nitroacetanilide from 4-bromoacetanilide result in crystallization?

Lymphocystis is an infectious disease of cultured and wild, freshwater and saltwater teleosts that affects a remarkably wide variety of fish from more than 30 different families (Lawler et al., 1977; Noga, 2010). The disease is one of evolutionarily advanced teleosts to date, not having been...
More data are needed, specifically from birds that preferentially or exclusively stop over and winter in freshwater habitats, to examine this question further. Notably, primarily freshwater and primarily saltwater wintering birds along the East Asian–Australasian flyway are parasitized by different ...
Coastal regions of Florida have so much saltwater that they must have freshwater piped in from inland areas, which has led to political disputes over control of the water supply. Water Regulation This aerial photograph shows damage to the Aral Sea caused by diversion of its water. Photo ...
Estuaries are widespread along the southern coast of the United States; they are formed by the mixing of freshwater discharge from some of North America’s largest rivers (e.g., the Mississippi, Brazos, and Rio Grande Rivers) with saline ocean water of the Gulf of Mexico. Estuaries of the...
Calculate how much pressure (due to the liquid) would be on an 83-kg person if they were 53 m deep in: a. freshwater. The density of freshwater is 1000 kg/m3. Express your answer in both pascals and atmospheres. 1 atm = 1.013 x 105 Pa. b. saltwater. The d ...
A boat floating in freshwater displaces water weighing 35.6 kN. What is the buoyant force acting on the boat? Classify the given situation as Archimedes' principle, Pascal's principle, or Bernoulli's principle to indicate which principle...
A boat floating in freshwater displaces water weighing 35.6 kN. What is the buoyant force acting on the boat? What is the buoyant force on a 465 cm^3 box which has 1/3 of its volume submerged in water? A 1.5 kg block displaces 4.0 kg of water when it is held fully immersed. What...
