| Desalinization of Water | | | Sara Reed‚ Myp2 | | Chemistry | | * Our world consists of 70% of water‚ from which‚ only 2.5% is fresh water‚ and 1% is drinkable water. Because of this low drinkable water rate‚ desalinization is a very important process which will help us provide a higher percentage rate. * Desalination is a process in which salt water is turned into fresh water‚ by extracting its water and minerals. Desalination is used on many ships and submarines

Water Balance Adipose tissue is one of the most hydrated of all tissues in the human body. False The most abundant cation in intracellular fluid is sodium. False Electrolytes determine most of the chemical and physical reactions of the body. True Solutes‚ regardless of size‚ are able to move freely between compartments because water carries them along the osmotic gradients.False The thirst center in the brain is located in the hypothalamus.True Dehydration can be caused by endocrine disturbances
