As glaciers melted at the end of the last Ice Age worldwide sea level increased immensely and river plains were flooded. Glaciers are floating bodies of ice. Ice is frozen water. When glaciers started melting water that had been frozen for decades or centuries was released back into the ocean. That lead to an increase in sea level. This also led to river plains being drowned/flooded. Therefore, the answer is 1 and 2.
<span>Answer: D. In the flavored water homogeneous mixture, water is the solvent and the drink mix is the solute.
Reasoning:
1) Powdered drink mix is a solid (powder) which is disolved,so it is a solute.
2) Water is a liquid in which the powder is disolved, then water is solvent.
3) All the powderred drink gets disolved as at the end is in aqueous form. Therefore, the mixture is homogeneous.
Then, you showed that the flavoured water is a homogeneous mixture, that water is the solvent, and that the powdered mix is the solute, which is what the statement of the option d. tells.

Naproxen is known to be a weak acid. In order to calculate
its ka and pka, use the equation of getting the ph of weak acid which is ph=
-1/2 log [(Ka)(Mwa)]. The Ka value is 3.18x10^-5. The pKa can be obtained
through pKa = - log Ka. The pKa is 4.5.
