Answer:
Hematocrit is a blood test that can identify anemia, dehydration and even heart disease. Generally, if the hematocrit values are too low, it can indicate the presence of anemia. If the hematocrit value is too high, the number of red blood cells in your blood is very high.
Explanation:
Hematocrit is a blood test that measures the percentage of the volume of all blood that is made up of red blood cells. If the hematocrit value increases, it is usually a sign that the body is not oxygenating well, and it compensates for it by increasing the number of red blood cells. If the hematocrit value decreases, it indicates anemia, the red blood cells or erythrocytes are cells capable of transporting oxygen to the tissues; Therefore, when they are reduced, a deficit of oxygen supply to the cells occurs, causing various symptoms. The heart tries to bring more blood supply to the tissues with the intention of increasing its oxygenation, for this reason the heart rate increases, producing tachycardias that are perceived as palpitations.

Answer:
Smaller the size of the DNA fragment, farther it moves during electrophoresis. The sketch of the position of the fragments has been drawn in the figure below.
Explanation:
As we know DNA is a negatively charged molecule. So during electrophoresis the fragments move towards the positive electrode because opposite charges attract each other.
Different fragment move different distances according to their size during the electrophoresis. Smallest segment travels the largest distance in the gel medium while the largest one travels least distance.
In the question there are four DNA fragments with base pairs 4000, 2500, 2000 and 400 so the smallest segment with 400bp will be farthest from the starting point and the largest fragment with 4000bp will travel least distance in the gel medium. Their respective positions are shown in the figure below. The starting point is near the negative electrode.
