I.Introduction Hydatidiform mole is a tumor that forms in the uterus as a mass of cystsresembling a bunch of grapes. Hydatidiform moles occur during the childbearing years‚ and they do not spread outside the uterus. However‚ a malignancy called choriocarcinoma may start from a hydatidiform mole. In its early stages‚ a hydatidiform mole may look like a normal pregnancy. Diagnosis is based on a history of lack of fetal movement‚ a pelvic examination‚ an ultrasound‚ and a blood test

normal pregnancy progress into a pathological one. It is characterized by the presence of a hydatidiform mole‚ which the chorionic villi around the fetus degenerate and form clusters of fluid-filled sacs‚ resulting in tumor growth that forms in the uterus as a bunch of cysts resembling grape-like vesicles that are visible to the naked eye. Hydatidiform mole (also known as hydatid mole or mola hydatidosa) is type a gestational trophoblastic disease that results from over-production of the tissue

I. INTRODUCTION Hydatidiform Mole (H-mole or Gestational trophoblastic disease) is abnormal proliferation and then degeneration of the trophoblastic villi (Garg & Giuntoli‚ 2007). As the cells degenerate‚ they become filled with fluid and appear as clear fluid-filled‚ grape-sized vesicles. The embryo fails to develop beyond a primitive start. Abnormal trophoblast cells must be identified because they are associated with choriocarcinoma‚ a rapidly metastasizing malignancy. (Pillitteri‚ 2010)

Convert from grams to moles using molar mass. To get moles from grams of potassium chlorate (KClO3): [molar mass = 122.55 g/mol] 138.6 g KClO3 X ( 1 mol / 122.55 g ) = 1.131 mol KClO3 3. Determine the limiting reagent [if necessary] (Use mole ratios to figure out.) * Not necessary to determine because there is only 1 reactant in this decomposition reaction. 4. Use ratios to find the moles of the reactant or product

this point‚ the reader can see her innocent as a child. She does not want to go to service not just because she scares to work‚ but she does not want to leave her nurse side. She does not have a mother‚ because of that she thinks her nurse as her second mother‚ because that’s the instinct of a child. The devil starts to play with her life after she’s starting to enjoy her life. Her nurse dies and she becomes a maid in a rich family. She has her first love when she’s there‚ but it is the start of

and a belief that we can make a difference. The term United Nations was first spoken by the United States President of the time Franklin D. Roosevelt. The notion of an organisation of this intention was first created in January 1942 (during the second World War) when representatives of 26 nations pledged their Governments to continue fighting together against the Axis Powers. Three years later representatives of 50 countries met in San Francisco at the United Nations Conference on International

Drew Moyer Mrs. Haire IB Chemistry Experiment 6 Mole Ratio in a Chemical Reaction Background: Mole ratios of reactants are often times figured out by the use of the other products in a chemical equation. However‚ in the instance that the products’ mole ratios are unknown‚ it can be determined through the experiment. This method is called continuous variations. In this lab‚ I determined the mole ratio between Sodium Hypochlorite and Sodium Thiosulfate by using continuous variations of ratios
