Answer:
C. A series circuit has only one loop and a parallel circuit has two or more loops for the current to flow through
Explanation:
A circuit that are made of one loop is called series circuit. On the other hand, the parallel circuit has at least two loops. The circuit type has nothing to do with open or closed circuit.
If any part of the series circuit got cut, the current will stop flowing since there is only one loop. A parallel circuit has more loop so the circuit might still work even if a part of the circuit got cut.

Why is the ocean water near the poles less salty than other places?
Question 8 options:
Rain washes mineral ions from the land into water.
Fresh water from the glaciers are melting into it.
Active underwater volcanoes erupt nearby.
Earthquakes shake rock loose nearby.
Answer:
Rain washes mineral ions from the land int water.
Explanation:
The amount of rain is highest at the equator and lowest at the poles. Due to this heavy amount of rain at the equator areas minerals get washed from land to the water. The washed minerals when be in the watery medium the either dissolve or dissociate to different ions according to their nature. The dissolution or dissociation of minerals in the water releases various salts in the medium and it becomes salty because of their presence in higher amounts.
Answer:
Fresh water from the glacier are melting into it.
Explanation:
Fresh water, in the form of water vapor, moves from the ocean to the atmosphere through evaporation causing the higher salinity. Toward the poles, fresh water from melting ice decreases the surface salinity once again. ... Adding salt to water lowers the freezing temperature.
