Blood is far denser than sea water as it has a whole bunch of cellular bodies mixed in with it.
I think you wanted to ask "Which is denser seawater or serum?" In that case serum is still heavier even though it has less salt. Serum still has a wide assortment of exotic proteins dissolved in it.
seawater
actually it's not. seawater has a pH of 8 making it a base.
Titanium and zirconium, for example, are resistant to corrosion in seawater.
When you drink seawater, a high concentration of salt finds its way into your blood vessels. As a result, you have a higher concentration of solutes (salt molecules, in this case) on the outside of your blood cells than in your blood cells-- there is a hypertonic solution on the outside of the blood cells. Your body wants to keep solutions isotonic across the membranes-- that means your body wants the same amount of free water molecules on the inside of the blood cells as the outside-- so water molecules move out of the blood cells in order to keep the balance of free water molecules. The water moving out of the blood cells cause them to "crenate," or shrink, which is of course not very good for your cells.
Lead is denser than iron.
Salt
riptide
yes because of the salt
the salt makes seawater denser than freshwater. more salt increases the density
Seawater because it contains salt which makes the water more dense than water which does not contain salt.
Nope; specific gravity is lower
probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
sea water is less denser than river water.
Because sand is denser than water. But I suspect you meant to ask "why is it easier to stay afloat in seawater than it is in fresh water". In which case the answer is the same: seawater is denser ... but not as dramatically, and the difference is small enough that you're unlikely to actually notice it unless you take careful measurements.
as u know, seawater is salty ,that is hypertonic.. when u place RBC in sea water it will swell and then burst.

Juice is much denser than oil. Juice will sink and some what combine with water while oil floats on top of water.
