Answer:
<em>The correct option is C) chlorine</em>
Explanation:
Sea water contains salts in abundance. It can be described as the water which makes up the oceans and the seas. It is known to contain approximately 96.5% water and 2,5 percent of salts. Sodium and chloride ions are the most abundant salt ions to be found in the sea. The concentration of chloride ions is 0.546 mol/kg and the concentration of sodium ions is 0.469 mol/kg. Hence, chloride ions are slightly abundant than sodium ions.
Frozen red blood cells that have been thawed, deglycerolized and reconstituted in an open system must be used within 24 hours.
Cryopreservation of Red blood cells (RBCs) can be done with a long time span of usability of 10 years. Glycerol safeguards RBCs during freezing and defrosting, yet it can cause hemolysis if it is not washed off or eliminated before transfusion. When a unit has been deglycerolized, the shelf life of RBCs in an open system is only 24 hours, bringing about sporadic utilization of Frozen RBCs from the outset of the procedure or in close system cases it is up to 14 days.

Scaled reptiles are the largest group of living reptiles.
<span>Food energy comes mainly from carbohydrates, protein, and fat from the food humans eat. Food energy usually comes from carbohydrates and fats rather than proteins. Energy is usually consumed because of various metabolic and enzymatic processes; and any excess in energy is stored as fat (in adipose tissue) and glycogen (in the liver and in muscles). Food energy that are not used are lost as heat<span>.

Answer: is 84.78 mm^2
Explanation:
we will first find out their areas, the area to be found is of a circle 
R^2
for the first one,
R=radius
pi=3.14
so,=3.14*(3mm*)^2
=28.26mm^2
for the second one
=3.14*(6mm*)^2
=113.04mm^2
their differences are equal to 113.04 - 28.26
=84.78 mm^2
