The sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin’s‚ Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels‚ less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged.This is what causes the problems of sickle

Christine Otieno Estimating Osmolarity of plant Cells(potato and celery)by percentage change in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease

will affect the beetroot cell membrane‚ I will keep the temperature constant throughout the experiment by using a water bath and measuring the desired temperature using a thermometer. PH: I will make sure that the pH is stable (constant) and only the temperature varies this is to be done by using buffer in every test tube so as to maintain pH balance for each beetroot sample and insure that pH does not become a variable. PH is important for maintaining the integrity of the cell membrane as integral

dioxide infused blood cell‚isn’t everybody?. I was made in the bone marrow along with all my brothers and sisters. Todays my 1st in the heart‚ and well I guess my first day to be alive really‚ I’m so excited. The heart would be my first trip well‚ anywhere really it’s truly amazing wait‚ unless you count the bone marrow. Did you know? I was only made about 5 seconds ago in your own bone marrow and now I’m headed for you’r heart. Okay so I’ll admit I’m scared‚ nervous‚ and excited you may be thinking

Stem Cell Culture Human embryonic stem cells are pluripotent stem cells derived from the inner cell mass of the blastocyst‚ an early-stage embryo. To culture these stem cells under controlled environments‚ one first must have a growth medium. This growth medium is made with DMEM/F12‚ which is cell culture medium‚ a 20 percent Knockout Serum Replacement‚ 100 μM β-Mercaptoethanol‚ 1 percent non-essential Amino Acid‚ and a Basic Fibroblast Growth Factor. This medium is then changed out everyday

Points‚ and Plan “Should regulations regarding the use of cell phones while driving be standardized?” On December 13th 2011‚ the National Transit Safety Board called for a complete ban on cell phone use while driving‚ arguing that even hands-free phone use was distracting and dangerous. However‚ two weeks later‚ U.S. Secretary of Transportation‚ Ray LaHood‚ said he would not endorse a ban. His justification was simply that hands free cell phone use was “not the big problem in America”‚ which in my
