BIOLOGY 1 PBL1 SICKLE CELLS DISEASE www.paatty.blogspot.com
The microorganisms and viruses studies are used because its needed for knowing the function of the sickle cell, and also the evolution and structure for knowing how it affects the organisms and the function .The sciences that are being used for the study are the chemistry for the study of the changes of the cell and the structure of the molecules of living organisms, math and geography for knowing the measure and the amount of the population that has the cell or predinct the amoung of persons that have the disease, computer science that counts and analyze and extracts the information of the sickle cell and it calculates and predicts the mutation in the DNA of the person and also the ethics are used because is needed for the persons permission for the practicing and using the new technologies for healing and it interacts with the disease and person.
The branches of biology that are used are the biophysics because it studies the physical process of organism, genetics is also used because the disease is passed through generations and calculated the variation of the disease, cytology because it studies the cell and its functions, anatomy because it considerate the structure of the structure of the living things, physiology because the cell affects the systems and this studies the function of the systems, evolution because of the sickle cell changes in the inherits traits in a population and microbiology for the sickle cell study.
The levels of organization that the sickle cell affects are: first the tissue because it doesn’t allows the oxygen pass trough correctly, then the organ because the tissue is part of the organ and the sickle cell affects the function of it , the system because it affects organs that are needed for certain systems for certain functions in the body and one of the systems that are affected is the nervous system because the lack of oxygen, then mostly the organism because it’s the caring person that is sick or mostly sick of the sickle cell because of the mutant cell on the DNA, finally the population because the disease pass from generation to generation.
The macromolecules involved in the sickle cell disease is the haemoglobin which has four globular proteins that forms a tetrahedral arrangement also the functions is that it pulls in oxygen and releases carbon dioxide that is also called the deoxygenation.
The levels of structure that the haemoglobin has is the fourth level because its tridimensional shape with the union of two or more polypeptide chain of sickle cell.
The level of structure that haemoglobin are affecting are the second, third and fourth because the non healthy heamoglobin changes the shape and structure of the cells and the blood it changes the attraction and arrangement between the cells.
The consecuences that the changes affects to the levels of organization are: first it starts with the DNA that has cells that are have the mutation that affects the tissue and a organisms itself , then this affects the system and the organism because of the haemoglobin lack of function. Finally it affects the population and could affect the biosphere if the disease isn’t controled.
The ethical prevention for stopping the spread of the sickle cell that used is the doctors doing research in the persons DNA and try to relate them to other people that doesn’t have the cell to avoiding the cell to pass to the next generation.
