Average density at the surface is 1.025 kg/L. The two
substance that can be seen in salt in sea water is sodium and chloride, seawater
has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium
(Na+) and chloride (Cl−) ions). Seawater is denser than both fresh water and
pure water (density 1.0 kg/L at 4 °C (39 °F)) because the dissolved salts
increase the mass by a larger proportion than the volume.
it is unique in being the only human bone that is not attached by joints to any other bone, but is suspended in the neck by muscles and ligaments alone.
Homeostasis is the term use to describe the internal stability needed for survival of an organism, including humans and animals while equilibrium is narrow to specific mechanisms.
