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>.

In the case of left-sided heart failure, blood backs up into the lung circuit. You would expect Mr. Kalani to have pulmonary direct result of this edema.
<h3>The effects of Left-sided heart failure</h3>
Left-sided heart failure occurs when the heart becomes unable to pump blood to the whole body. This is because the heart can not handle the blood that is coming from the lungs.
When left-sided heart failure occurs, fluid leaks from the affected capillaries into the nearby tissues of the lungs circuit leading to pulmonary edema.
Excess fluid in the tissues is called edema and in the case of a left-sided heart failure, other parts of the body such as the feet, legs and ankle are equally swollen.

The flow of energy is always one way. If we start at the sun and the sun’s energy moves to a plant, then the plant cannot transfer that energy back into the sun. The flow of energy is always controlled bc there is always a visible path it takes.
Answer:
d) passage of a solute against its concentration gradient
Explanation:
When a solute is transported against its concentration gradient, the cells use metabolic energy. To move a substance from the region of its lower concentration to that of its higher concentration, the energy of ATP hydrolysis is utilized. These types of transport mechanisms are called active transports. If ATP hydrolysis is inhibited in a cell, it would not be able to perform the uphill movement of solutes due to the lack of any source of energy to drive the process.
