DNA move through an agarose gel because DNA molecules are negatively charged due to the presence of phosphate groups in their sugar-phosphate backbone which make them to move toward the positive charge in the agarose gel.
<h3>What is DNA?</h3>

You should wash your cut before and after swimming so that bacteria in the water can't infect the wound.
Let me know if its right <3
Whales are closely related to hoofed mammals with an even number of toes, such as horse, because they evolved from them. Before whales were what we know them as today, they were relatively similar to horses. They used the water to flee from predators, and they evolved slowly to heighten their swimming ability, eventually becoming modern day whales. Fish have always been aquatic animals that have gills. Whales cannot breathe underwater, so they take in oxygen the same way a horse does. Also, both horses and whales are mammals that give birth to their offspring and are warm-blooded. Fish lay eggs and are cold-blooded.
