Answer:
Estuaries are often called the “nurseries of the sea”
Explanation:
Because so many marine animals reproduce and spend the early part of their lives there.
The final gas pressure : 175.53 atm
<h3>Further explanation</h3>
Maybe the complete question is like this :
A ridged steel tank filled with 62.7 l of nitrogen gas at 85.0 atm and 19 °C is heated to 330 °C while the volume remains constant. what is the final gas pressure?
The volume remains constant⇒Gay Lussac's Law
<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature </em>
P₁=85 atm
T₁=19+273=292 K
T₂=330+273=603 K

Answer:
Number of grams of mineral salt in one liter of water
.
Explanation:
Salinity :
It is the concentration of dissolved salts .
Salinity means the saltiness or the dissolved salt component in the water body . It is defined as mass (in gram) of the dissolved matter in the water bodies .
salts found in ocean water are :
Salts of chlorides, sulfates , sodium , magnesium, potassium and calcium
For example : world's oceans salinity is 3.5% parts per thousand (g/L) . It means 3.5 g of salt is present in 1 L of seawater .
Note : Sodium chloride is major salt found in ocean . But it is not the only salt present (other salts are also found) . So D can't be the answer
