Lane A.

The smallest fragments of DNA will be witnessed near the bottom of the gel, on the other hand, the heavier fragments will be visible at the top. The theory behind this is there is a specific pore size on the basis of the concentration of acrylamide/agarose in the gel.

Winds in our atmosphere are created as a result of which of the following processes?
shusha [124]

Answer:

<em>The correct option is D) Uneven heating of the air in the atmosphere</em>

Explanation:

Wind can simply be described as air which is moving or which is in motion. The uneven heating of the Earth's surface caused by the sun is the reason why winds occur. The difference in pressure of one area to another area causes the air to move and cause wind. The air tends to move from an area of higher pressure to an area of lower pressure and such is the movement of the wind.

xeze [42]

Answer:

Left ventricle.

Explanation:

Human heart is divided into four chambers - two auricles and two ventricles. Heart acts as the pumping organ and carries both oxygenated and deoxygenated blood in the right and left ventricles.

The failure of functioning of any chamber of heart may cause a particular disease in the individuals. The pulmonary congestive heart failure occurs due to the failure of the left ventricles of the heart. The left ventricle carries blood from heart to the body tissues, its failure leads to the backup of blood in the lungs.

Thus, the answer is left ventricle.
