Salt wedge

Explanation:

"An estuary that is found within the mouth of a river where freshwater flows out to sea at the surface while seawater flows upstream along the bottom is a Salt wedge."

Salt-wedge estuaries take place when a rapidly moving river joins the ocean from the point of weak tidal currents. In such kind of salt estuary, the force of a river is responsible for pushing the water out to sea rather than upwards and is also a factor that determines the circular motion

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.

answer; first blank(1); 30% two(2); salmonella; i believe this is correct; //good luck;
