Evolution of Sickle Cell Sickle Cell was discovered in the United states although it originated in Africa . The sickle cell disease (SCD) describes traits of an inherited red blood cell disorder‚ having SCD means you have abnormal hemoglobin‚ called hemoglobin S or sickle hemoglobin‚ in your red blood cells. What is hemoglobin u might ask?! Well Hemoglobin is a protein in red blood cells that is suppose to carry oxygen throughout the body. But when a sickle cell trait is “Inherited” it could

el A.) Cell theory : 1.) All organisms are made of cells. 2.) All existing cells are produced by other living thing. 3.) The cell is the most basic unit of life. B.) Contributors to the Cell Theory: People | Information | Hooke | He was the first to identify cells and he also named them. | Leeuwenhoek | He made better lenses so he observed cells in greater detail. | Schledien | He was the first to note that plants are made of cells. | Schwann | He concluded that all living

the use of cell phones? According to scientific evidence cell phones may actually be more harmful than you think. I believe cell phones are dangerous to our health because they have been linked to causing tumors‚ can affect your eye health‚ and they also hold a lot of bacteria. Cell phones have more serious risks than they do benefits. Therefore it is better to limit how much you use your cell phone. It has been scientifically proven that you can actually get a tumor from the use of cell phones. These

Cell City Cell City A cell is like a city. They both have parts that play different roles. A cell is microscopic that has organelles‚ and a city has different services. Keeping them both running smoothly and orderly. As a result they both survive and grow. There’re a lot of different organelles in a cell that are similar to a city for example the cell membrane borders and protects the cell it’s role is letting certain things in and out of the cell in the same way a border in a city does.

him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the mutated gene. The blood cells form an abnormal crescent shape (normal cells are in a disk form). The

The effect of temperature on beet cell membranes Introduction: A cell membrane of a beet (Beta Vulgaris) is made up of a phospholipid bilayer with embedded proteins and cholesterols. The membrane is responsible for organizing the cell‚ protecting it from the exterior environment‚ as well as responsible for regulating what goes in and out of the cell though it’s protein channels and “selectively permeable” bilayer. (Campbell‚ Reece‚ Taylor & Simon‚ 2006‚ p. 79-80) When this membrane is damaged

Most schools now allow students to have cell phones but try to require them to be turned off during class because they can be disruptive and distracting
