Here is the simple answer:
It basically rips the DNA into pieces and those pieces are placed into the gel. The gel has holes throughout the contaioner and allowing the DNA pieces to wiggle through. These are pulled by an electric potential (or voltage) that attracts the DNA pieces. The larger the piece of DNA the shorter distance it will travel through the gel.

Answer:
The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.
Explanation:
In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.
In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.
