  • Lab Report Diffusion And Osmosis

    found out about diffusion which can happen as active transport or passive transport. Diffusion is known as delivering a net development of solute particles from locales of higher focus to districts of lower concentration. Active transport is the development of an atom over the plasma layer. Active transport is when atoms move against their focus slopes. We discovered that dynamic transport requires vitality, and the motivation behind this test was to comprehend the procedures of diffusion and…

  • Diffusion In Agar Cubes Experiment

    Diffusion in Agar Cubes Experiment Introduction Diffusion is a paramount process to organisms because molecules enter the body cells and waste products are removed. Diffusion is the movement of particles from regions with dense areas to regions with lower density. Diffusions rate can be determined by many factors this includes, the size, synthetic composition, concentration gradient, surface area to volume ratio. The independent variable in this experiment is the size of the agar, this means…

  • Porous Ceramics Essay

    (IV) Porous Ceramics The concept behind nearly inert, micro-porous bioceramics (type2) is the ingrowths of tissue into pores on the surface or throughout the implant. The increased interfacial area between the implant and the tissues result in an increased inertial resistance to movement of the device in the tissue. The interface is established by the living tissue in the pores. This method of attachment is often termed biological fixation. It is capable of withstanding more complex stress…

  • Solid Solubility Lab Report

    6/ Since this is a furnace means that it will always at high temperature so it would be inefficient to just using the sources at solid because it took time to sublime that solid and turn it into gaseous state for diffusion sources. The best efficient way is to use a gaseous diffusions sources. We got 2 candidates PH3 and POCl3. PH3 has a little quirk that escaping gas cannot be extinguished and exposure to fire may cause containers to rupture. This is a high temperature furnace which we will…

  • Colligative Properties In Chemistry

    Colligative properties are the physical changes that result from adding solute to a solvent. Colligative properties depend on how many solute particles are present as well as the solvent amount, but they do not depend on the type of solute particles, although do depend on the type of solvent.2 With this, the van’t Hoff factor must also be included. Colligative properties are used in people’s everyday life when it comes to osmotic pressure, boiling point elevation, and freezing point depression.…

  • Ap Biology Dialysis Experiment

    Our goal of the dialysis experiment was firstly, to answer the question of why the dialysis cells appeared smaller after adding sugar water and secondly, to prove our hypothesis that water molecules move out of the cell because the concentration of water is greater than inside the cell than it is outside the cell. This experiment was conducted with one control group and one experimental group. The independent variable was the concentration of water, (water and glucose solution). The dependent…

  • Hypertonic Egg Lab Report

    In this experiment I attempted to created and study the affects of a egg in a hypertonic and hypotonic solution. To conduct this experiment I used the following materials: cups, eggs, vinegar, corn syrup, spoons and food coloring. To begin the experiment I placed three eggs in vinegar to dissolve their shells, leaving behind a thin membrane that allowed water to pass in and out of the eggs. The water molecules enter inside the eggs and the eggs begins to swell. Once the eggs have sat in the…

  • Egg Osmosis Egg Lab Report

    view the effects of an egg in a hypertonic state, hypotonic state, isotonic state and diffusion. Hypertonic is the movement of water leaving the egg to an area of higher concentration. When this occurs the egg becomes shriveled. Hypotonic is the process of water moving into the egg from the outside; the egg becomes swollen. Isotonic is when the water concentration is the same inside as is it on the outside. Diffusion is the movement of solute, a substance, from a high concentration to an area…

  • Egg Hypothesis

    Eggsperiment Purpose Is an egg similar to a human cell? Hypothesis If the egg is put in milk, then the shell will grow back. According to Mama Natural, “High-quality eggshells contain 27 essential microelements but they’re mostly composed of calcium carbonate, a form and structure that’s very similar to our bones and teeth.” Also, according to My Plastic Free Life, “eggshell powder contains roughly 400 milligrams of calcium per gram.” Since the milk I use, 2% Fat, has 295 milligrams in one cup…

  • What´s Multiparticulate Drug Delivery System?

    Reservoir Systems consist of a hollow inner core and a polymer membrane, there to control the rate of drug diffusion. Drug diffusion across the membrane is rate limited and controls general drug release rate (Bajpai et al. 2008). For reservoir systems drug release normally remains steady resulting in a zero order profile (Raval, Parikh and Engineer, 2010). Another technology is called the Multiparticulate drug delivery system which consists of microencapsulated granules/beads containing drug…
