Week 3 - Essay Example It also involves three important elements which include availability, accessibility and food utilization (Food & Culture Encyclopedia). When food security is threatened or not met, it can alarm not only the nutritionists, but the country or the nation affected, in general. This is because if there will be inadequate supply of food and related goods, it will directly affect the health and nutrition of the people. Thus, food insecurity can cause individuals, families, communities and to some extent, the world, to suffer in varying degrees. The Dictionary of Medical Terms defined malnutrition as a state or condition wherein a person is deemed as having a poor nutrition that resulted from either an insufficient, excessive, or unbalanced diet or in disorders in which there is an impaired ability to absorb and assimilate foods (Rothenberg and Chapman 269). Meanwhile, obesity is a malnourished condition of having an excessive weight and an increased amount of fat in subcutaneous tissues of the body. Obviously, obesity is the effect of overeating, but in some cases, it may be precipitated by disorders that involve organs such as thyroid, pituitary and endocrine glands where there is a disturbance of the body’s metabolism (Rothenberg and Chapman 318). Today, an alarming statistics states that approximately 60 million Americans are obese, while 9 million are extremely obese (ObesityinAmerica.org). Hence, according to Mokdad, et al, obesity has been regarded as the second cause of preventable death in the US (qtd. in Ob esityinAmerica.org). Suppose that you were engaged in biotechnology, or genetic engineering; what environmental safeguards would you impose on your own research? Are there experiments that would be ethically off-limits for you? If I were to engage in genetic engineering projects, or related experiments, conscientiousness on my part would be necessary, so as to

As the curved piece blocks the moving red pieces it represents the red blood cells being affected by the sickle as they move and changes their shape to oval. What happens is that the sickle celled cells get stuck on the way just like the stopped red piece when they are moving in the blood vessels. As a result oxygen is stopped from being distributed into the body causing pain in the sick body. This effect can affect other body parts like the body organs, the bones and the muscles. This model art represents the affected cells and their movement. The two pendulums represent the pumping of blood in the human body. As the pendulum swings, it introduces a new force and makes the pieces to move. As one square piece moves, it exerts force to the other piece making them to move slightly. The small square pieces represent the affected cells which do not move to circulate oxygen to the entire body of a human person. This creates redundancy in the blood cells movement hence oxygen is not circulated fully. People with sickle cell disease face a lot of pain and problems and hence their life span is reduced. This is one of the best visual arts represented which clearly shows how the affected red cells find it difficult to move in the blood vessels. The tray in which the square pieces move represents the blood vessel. Ever taught the cause of Sickle Cell? Well, it is a disease that is normally inherited mostly from a parent to a child. The child is so unlucky that he or she gets a gene from each of the parents (Father and Mother). When a child carries only one gene of the Sickle cell, he or she becomes a carrier. From this simple explanation, you now know how sickle cell
