Cancer Epidemiology Cancer is not a single disease; it is a myriad or collection of diseases with many different manifestations as there are many different types of tissues and cell types Cancer is a disease of abnormal gene expression. Cells are constantly evolving and have the natural selection pressures to change Common biological properties of tumor cells: 1) Deregulated clonal cell growth- all cells in a tumor originated from one single cell that acquired mutations that made it deregulated

Largest Gypsum Crystals A mile below one of Mexico ’s most important lead and silver mines‚ and a few miles above the earth ’s magma lies a magnificent Geological Wonder. It Is Known As “The Cave Of Crystals." It contains the largest gypsum crystals known in the world to date. The cave was discovered in 2000 by two brothers drilling 1000 feet below the ground while working for Penoles mining company (Garcia-Ruiz et al.). Man and mining have had a negative impact on the crystals‚ and should be

the growth rate of crystals The information gained from this experiment can help society by showing different temperatures can affect the growth rate of different types of matter; also it may help computer chip manufacturers‚ as there are crystals in computer chips. Temperature affects the way crystals grow through molecule movement. Higher the temperature‚ warmer the crystal solution‚ faster the molecule

Liquid Crystals from Coconut Oil Fatty Acids - Investigatory Project Liquid Crystals from Coconut Oil Fatty Acids Abstract Liquid crystals are fluids that are between the solid and conventional liquid phases. Liquid crystals are in widespread use‚ especially in optical technologies. They are synthesized by combining fatty acids with cholesterol. This study aims to utilize coconut oil as an alternative source of fatty acids for synthesizing liquid crystals since coconut is cheap and abundant
