Answer:

The direction the blood takes through the circulatory system is important because it makes sure that the nutrients and blood gets to every organ and vein in our body. the direction the blood flows is this. Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart. so we can be the living breathing people we are today.

Why does DNA flow toward the positive electrode of the gel chamber?

Digiron [165]

Answer:

DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole.

Explanation:

Electrophoresis is a technique that uses differences in electrical charge to separate the molecules in a mixture. DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole. The rate of migration of a molecule depends on two factors, its shape, and its charge-to-mass ratio.

A gel, which is usually made of agarose, polyacrylamide, or a mixture of the two comprises a complex network of pores, through which the DNA molecules must travel to reach the positive electrode. The smaller the DNA molecule, the faster it can migrate through the gel. Gel electrophoresis, therefore, separates DNA molecules according to their size.
