what do biologists study changes in amino acid sequence when trying to determine causes of genetic variation?
baherus [9]

Answer:

reason for studying human genetics is that it gives us a powerful tool for understanding and describing human evolution. At one time, data from physical anthropology (including information about skin color, body build, and facial traits) were the only source of information available to scholars interested in tracing human evolutionary history. Today, however, researchers have a wealth of genetic data, including molecular data, to call upon in their work.

charle [14.2K]

Answer:

The correct answer would be the pulmonary vein and the superior vena cava.

Pulmonary vein is a blood vessel of pulmonary circulation which carries oxygenated blood from lungs to the left atrium of the heart. Hence, it is rich in oxygen and carries carbon dioxide in the least amount.

In contrast, vena cava is a part of systemic circulation and carries deoxygenated blood from the body to the right atrium of the heart. They are two venae cavae in human beings namely; inferior vena cava (carries blood from lower body) and superior vena cava (carries blood from head, arms and upper body). Hence, it contains maximum carbon dioxide and least oxygen.
