History Midterm - Term Paper Example A detailed introspection into the history of both the ancient civilisations would culminate into the fact that both the civilisations developed in the basin of the great rivers which not only provided a life – line to the population but also provided most favourable conditions for the development of civilisation and human settlement. Yet there is a vast difference in the nature and development of the Mesopotamian and Egyptian civilisations. Mesopotamian civilisation gradually became the rink for the Romans and the Parthians. The part of Mesopotamia concentrated on the Assyrian region was gradually taken in control by the Romans for a time being and gradually it fell into the hands of the Sassanid Persians and remained so till 7th century. Between 1st century BC and 3rd century AD, many neo-Assyrian and Christian native Mesopotamian states existed. Whereas, the Egyptian civilisation had a peaceful rule till it was conquered by foreign powers in the later period. It reached the omnipotent regime of power during the Rammesside period. The success of the Egyptian civilisation can be found in its extreme adaptability with the changing conditions of the Nile River Valley. The flooding was predictable and the over-fertile Nile basin produced surplus crops which initiated the development of the Egyptians socially as well as culturally. If I would have been a peasant in the 2nd Millennium BC, then I would have definitely chosen Egypt for the place of settlement because during that time Egypt was the only civilisation which had a very peaceful and calm geographic and social environment which accelerated its development and prosperity. In Egypt, there was a huge prospect for the farmers. Irrigation facility was evident and the floods were predictable. The soil was extremely fertile and it provided the best opportunities to grow more and good crops. In Mesopotamia, the conditions for the cultivation were favourable. It was

The different types of protein defects that can be associated with the red blood cell - Essay Example RBCs give blood its characteristic red color†. Hemoglobin is a metalloprotein, which means it is a protein that includes iron as one of its constituent atoms. For the reason of oxygen distribution, hemoglobin has multiple chemical â€Å"slots† for storing oxygen. This oxygen is acquired from the heart, where red blood cells are replenished with oxygen from the lungs. According toToole(2004: 32) â€Å"Red blood cells are unusual in having no nucleus, mitochondria and they are much thinner in the middle and so form a biconcave shape†. The red blood cell is the main component of the circulatory system, also known by the name of cardiovascular system. In the circulatory system, the channels know as arteries hold oxygen-rich blood for distribution to the body, while veins give back oxygen-poor blood to the heart for replenishment. The oxygen levels of blood can be assessed by looking at its color – oxygen-poor blood has bluish color, while oxygen-rich blood looks red. The second important function to carrying oxygen although less commonly known, is the capability of red blood cells to carry carbon dioxide. CO2 is a waste product formed due to metabolism in every cell in the human body Red blood cells measure a diameter of about 6-8 micrometers (millionths of a meter), similar in size to much of the cells in the body. An RBC is biconcave in shape.Rosenberge (2010)states that â€Å"Red blood cells completely lack in most other common cellular parts, such as a nucleus with DNA, or mitochondria†. Due to their small shape and physical structure, the RBC can squish in to the small capillaries where the blood vessels are the smallest. Without this nature of flexibility , they have a high chance of getting stuck and cause obstructions in the circulation Because red blood cells are so important to your body, when they dont work properly, it often leads to
