Sickle cell anemia is a blood disorder that affects the 11th chromosome which is a hemoglobin gene. Hemoglobin is a protein located in red blood cells (RBCs) that carries oxygen through the body. This disorder is inherited from two parents with abnormal genes that are heterozygous (Rr). This means that both parents who have the trait may pass on the disorder to their offspring. The phenotype makeup is recessive. Those who inherit a normal copy of the chromosome 11 and a mutated chromosome will carry

Euglena cells contain a variety of cellular constituents‚ their cellular constituents should be presented in equal ratio. The objective of this experiment is to determine Euglena’s cellular components in cells and then to establish their cellular constituents by comparing the experimental results to the expected concentrations given on pg 10 of the lab manual. Concentration of cells in stock culture used for extraction =9.0×105 cells/ml Total number of cells used for

Cell Membrane Transport The purposes for these experiments is to be able to understand osmosis and its relationship to tonicity of solutions‚ and the transportation of molecules across cell membranes. It’s also used to understand‚ and how temperature affects diffusion. You also learn how to test for presences of starches and sugars in solutions. In the first exercise I will be testing for diffusion through an artificial membranes. This one has forty five steps to it. I will not go into

Topic: Using Cell Phones Most cell phone companies design models especially for kids. But parents are usually the ones buying the phones‚ and paying the bills. According to a July 2012 study‚ 56% of parents of children ages 8 to 12 have given their children a cell phone. The percentage goes up with age. The study‚ by ORC International for the National Consumers League (NCL)‚ basically proves what many people already assumed: many kids‚ if not most‚ have their own cell phones. According

century‚ little was known about cell membranes. Until the early 1950s‚ the biological cell membrane was rarely mentioned in scientific literature. It was recognised that something was probably there‚ but hardly anything about it was known. Considering the lack of technical equipment available a century ago‚ scientists such as Charles Overton and Edwin Gorter were not only exploring new territory in looking at the properties of cell membranes‚ but laying the way for future cell biologists. Scientists had
