<h2>Answer:</h2>
<u>the movement of water from ocean through the atmosphere and back is called </u><u>the water cycle</u>
<h2>Explanation:</h2>
The water cycle describes the process that how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. The earth has a limited amount of water. That water keeps going around and around what we call the "Water Cycle".
Answer:
The longest strand of DNA is the one that has descended the least in the electrophoresis gel. In other words, it is the one at the top of the gel.
Explanation:
Electrophoresis is a process that separates DNA according to its size and charge. The scientist puts the DNA samples into the indents at the top of a special gel. Then the person places it in a box that contains an ionic solution, a positive electrode at the bottom, and a negative electrode at the top. As the DNA has a negative charge, it will descend through the gel's pores towards the positive electrode. Since there are DNA of different lengths, the shortest goes down quickly through the gel than the large strands. As a result, the short strands of DNA will be at the bottom of the gel, the medium size strands will be in the middle of the gel, and the l<u>arge strands on the top of the gel</u>.
