In this work, several simulations and analyses are carried out to investigate the feasibility of generating electricity from underwater sea currents at Istanbul Bosphorus Strait. Bosphorus is a natural canal which forms a border between Europe and Asia by connecting Black Sea and Marmara Sea. The differences in elevation and salinity ratios between these two seas cause strong marine currents. Depending on the morphology of the canal the speed of the flow varies and at some specific locations the energy intensity reaches to sufficient levels where electricity generation by marine current turbines becomes economically feasible.
In this study, several simulations are performed for a 10 MW marine turbine farm/cluster whose location is selected by taking into account several factors such as the canal morphology, current speed and passage of vessels. 360 different simulations are performed for 15 different virtual sea states. Similarly, 8 different configurations are analyzed in order to find the optimum spacing between the turbines. Considering the spatial variations in the current speed within the selected region, the analyses are performed for three different flow speeds corresponding to ±10% change in the average value. For each simulation the annual energy yield and cluster efficiency are calculated.
Human evolution known to be a process in which species adapt to certain conditions of life, and in the battle of life and death, they are forced to become stronger in order to survive in this world. Diseases have always been present during the evolution, acting themselves as a natural selectors - the weaker organisms get sick and die. Not just humans, but all species have to establish a great protecting mechanism in order to survive. That is how our bodies are built, to be able to withstand and survive in the conditions we live in, and that is why our immune system has to be taken care of.

Answer:
The Circulatory or Cardiovascular System
Explanation:
This system allows the circulation of blood to every cells of the body with the transport of oxygen and nutrients essential for its survival. These nutrients include glucose, amino acids, vitamins, minerals and so on produced by the body through metabolism.
The circulatory system comprises also of the lymphatic system, which allows for the flow of lymphs.
The circulatory system is made up of systemic and pulmonary circulation. The heart and blood vessels being the major structures in this circulation. The blood moves to the lungs and get oxygenated (pulmonary circulation) and it then returned back to the heart for transport to other parts of the body known as the systemic circulation. Hemoglobin, which carries oxygen in the blood and also carbon iv oxide for excretion out of the plasma. From the digestive system, the nutrients are absorbed into the blood plasma and then transported for the cell use or for storage.
