There are over 100 different types of cancer. Each type of cancer can have different symptoms‚ diagnostic tests and treatment options. As a result‚ there are many terminologies and phrases that are used to describe the type‚ symptoms and diagnosis of cancer‚ and treatment methods. It is often very confusing as well as frustrating for the readers if too many medical jargons or terminologies are used in describing this condition. It is difficult for readers to understand the context of the topic or

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

was then used to transfer 4ml of anhydrous ether to the vial. The syringe was then utilized to transfer 0.8 ml of this solution and the reaction was allowed to proceed until the solution turns brown and cloudy. The conical vial was then rinsed with 2 ml of anhydrous ether to get any remaining solution into the reaction vessel. Simultaneously‚ 1.09 g of benzophenone and 2ml of anhydrous ether were added to a 3ml conical vial and gently stirred. The reaction vessel was taken off of the hot plate and

HOW THE CELL CYCLE OPERATES A cell is a dynamic system. It is "born‚" lives‚ grows‚ reproduces‚ and dies. Each cell works like an automated factory‚ duplicating parts of it. It interacts with its environment‚ sending and receiving signals—electrical and chemical—to act on or cause action elsewhere‚ and guarding against invaders or aggressively attacking other cells. A cell changes shape‚ moves off to another place‚ and sometimes links up with other cells. There used to be two cell-cycle theories

Cancer is a genetic disease requiring a series of change. Carcinogenesis is the development of cancer. Cancer cells are abnormal cells and they have characteristics that can be associated with their ability to grow uncontrollably. Cancer cells are non-specialized‚ and divide uncontrollably. Cancer in situ is a tumor located in its place of origin. Malignant tumors establish new tumor distant from the primary tumors. Cancer cells characteristics distinguish them from normal cells. They have abnormal
