1. One patient has a grade I tumor of the lung‚ while another patient has a grade IV tumor of the lung. Explain how tumors in various stages are similar and how they differ. (1 point) Both stage I and stage IV lung cancer is presented with cellular differentiation‚ loss of normal tissue structure‚ as well as irregular size and shape of the nucleus. Normal cells are able to divide and die cancer cells are pile up on top of each other forming a tumor. The staging and grading of cancer depends on

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

VOL. 70‚ NO. 5‚ MAY 1982 Silicon as a Mechanical Material KURT E. PETERSEN‚ MEMBER‚ IEEE Abstract-Single-crystal silicon is being increasingly employed in a variety of new commercial products not because of its well-established electronic properties‚ but rather because of its excellent mechanical properties. In addition‚ recent trends in the engineering literature indicate a growing interest in the use of silicon as a mechanical material with the ultimate goal of developing a broad range

Communication‚ Homeostasis & Energy Communication & Homeostasis Outline the need for communication systems within multicellular organisms‚ with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli‚ e.g. temperature‚ oxygen concentration and levels of sunlight. These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal

energy where as active is reactive Diffusion and Osmosis are important to know Having such knowledge will make your brain grow! I chose osmosis and diffusion because it is relevant to what we have learned over the past couple of weeks. As the lab manual defines‚ diffusion is the net movement of molecules from an area where they are high in number or concentration to an area of where they are less concentrated. Diffusion is important because it makes it possible for the random movement of molecules

They have found ways to fix genetic mutations‚ cure diseases‚ and even just improve a child’s athletic or intellectual ability. Genetic Scientists are trying to genetically engineer children in the womb‚ but genetic engineering is an inferior practice because of the safety‚ financial‚ and ethical issues. First‚ as our society gets closer and closer to genetic perfection‚ it has to monitor the safety of it’s people. When
