Donating Blood Imagine that your father had just suffered a heart attack‚ and has to go through open-heart surgery in order to repair the damage that happened to his heart. Imagine your little nephew or niece was born with a rare heart defect and had to have a daily transfusion of blood in order to have a chance to wake up the next day. Imagine that your best friend went to the doctor and had just been diagnosed with leukemia‚ a disease requiring regular platelet transfusions. These aren’t

Introduction This experiment was osmosis and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs‚ and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs‚ then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs‚ again the

molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent‚ each containing different concentration levels‚ then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell‚ but there is no net diffusion of water. Water will move in

Blood will Have Blood “These deeds must not be thought / After these ways; so‚ it will make us mad”(II‚ ii‚ 32-33) Translation today: A guilty conscience can make a man go crazy. In the play Macbeth‚ this is a recurring theme throughout one of Shakespeare’s most famous tragedies. There are many different images that help contribute to this theme such as sleep/sleeplessness‚ water‚ & children‚ but the most significant image would probably that of blood. Throughout

Animation: Cells & Chemistry Glycolysis After viewing the animation‚ answer these questions. 1. Cells derive energy from the oxydation of nutrients‚ such as glucose . 2. The oxidation of glucose to pyruvate occurs through a series of steps called glycolsis . 3. How many carbons are in a molecule of glucose? 6 4. The energy related during these oxydation reactions is used to form adenosine triphosphate (

A red–black tree is similar in structure to a B-tree of order[note 1] 4‚ where each node can contain between 1 to 3 values and (accordingly) between 2 to 4 child pointers. In such B-tree‚ each node will contain only one value matching the value in a black node of the red–black tree‚ with an optional value before and/or after it in the same node‚ both matching an equivalent red node of the red–black tree. One way to see this equivalence is to "move up" the red nodes in a graphical representation

Respiration is the process by which energy is released energy from glucose in the presence of Oxygen‚ forming carbon dioxide and water as waste products. Glucose releases energy in a series of reactions that take place inside components of the cell. The stages are briefly explained below as were briefly explained in part A‚ the process then goes through‚ glycolosis‚ link reaction and then the Krebs cycle. The volume of CO2 that is produced in the Krebs cycle is important as this is the dependant

LAB REPORT 1 - LAB 7 CELL MEMBRANE FUNCTION Marisela Camacho Legarreta June 30‚ 2013 ACTIVITY 1 INTRODUCTION Be aware that all molecules have kinetic energy‚ which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration. METHODS Check the reaction of different
