Molar pregnancy is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus and converts a normal pregnancy into an abnormal one (which will fail to come to term). A molar pregnancy is a gestational trophoblastic disease[1] that grows into a mass in the uterus that has swollen chorionic villi. These villi grow in clusters that resemble grapes.[2] A molar pregnancy can develop when an egg that is missing its nucleus is fertilized and that may or may not contain fetal

Determining the Molar Mass of an Unknown Solute by Freezing Point Depression Introduction: Colligative properties of solutions are only influenced by the concentration of solute particles and are independent of the nature of the solute. Some examples of colligative properties are boiling point elevation‚ vapor pressure lowering‚ and freezing point lowering (depression) (Brown‚ 542). For a substance to freeze‚ the kinetic energy of the particles must be low enough for the

The Nervous System: Ion Channels 1. What structures in the cell membrane function as ion channels? Intergral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? a. Charge on ion (+ or -) b.Size c. The amount of water the Ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an non-gated channel. 4. Would

The Effect of Common Bactericidal Agents on Staphylococcus Epidermidis Introduction Staphylococcus epidermidis is a facultative anaerobic bacterium. It is part of the normal human flora and is found on the skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems‚ open

Aim To investigate the effect of molar mass on the molar heat of combustion of adjacent members of a homologous alcohol series. Introduction Chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance. The heat of reaction is determined by the difference in the enthalpy between the reactants and products. The molar heat of combustion of a substance is the quantity of heat liberated when one mole of that substance is burnt completely in air. In the case
