Lopez‚ Jaymie A. D2B World History and Civilization 1 August 4‚ 2014 MY REFLECTION I choose Social Science as my major because I wanted to know a lot more about the field of economics and our history not only our history but the history of the whole world which made me get the WHISCVI1 subject‚ In this subject the use of technology was demanded. There were multiple assignments‚ quizzes‚ and reports. Using powerpoint presentation as our visual aids in sharing our knowledge is very important. Incorporating

METHODOLOGY After formulating the hypothesis that the molecular weight affects the rate of diffusion‚ three different kinds of substances --potassium permanganate (KMNO4)‚ potassium dichromate (K2Cr2O7) and methylene blue (C16H18N3SCl)‚ were used to test the validity of the hypothesis. Potassium permanganate is an inorganic chemical compound which is in violet liquid form; potassium dichromate is an orange inorganic chemical reagent and methylene blue is a chemical compound commonly used for staining

Title: Diffusion Rate of Methylene Blue on Agar Plates at Different Temperatures Abstract: Diffusion is the movement of particles from an area of high concentration to an area of low concentration wherein substances are independent‚ rapid and in random motion which frequently collide with each other in the sides of the container. This study aimed to assess the influence of temperature on the diffusion rate of methylene blue on agar plates. To determine the relationship between the two variables

Culture is by definition smaller than a civilization. 2. .Culture can grow and exist without residing in a formal civilization whereas a civilization will never grow and exist without the element of culture. 3. Culture can be tangible or intangible whereas civilization is something that

solutes move via passive diffusion through the plasma membrane. Diffusion is a process where molecules move from an area of high concentration to an area of low concentration. How quickly diffusion occurs is dependent on several factors‚ such as temperature‚ particle size‚ and the concentration difference on either side of the membrane. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate‚ agar plate set-up was used to observe the diffusion of different substances

the aim and background information 2.1. Diffusion is the spontaneous kinetic movement by which molecules move from an area of a high concentration to an area of low concentration. Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature‚ Concentration and Surface area

Change over Time Essay: Mesopotamia from 2000 BCE to Current Day The earliest civilization in Asia arose around 3500 BCE in Mesopotamia meaning "land between the rivers" because of its convenient location between the Tigris and Euphrates rivers. This river valley region’s rich soil and access to waterways made early civilization thrive on agriculture and trade. Although much has changed since its beginnings‚ the Mesopotamian River Valley has continued to grow and develop as a civilization to

Medicine and surgery have come a long way from what they used to be. Back in ancient Rome and Mesopotamia they were removing arrows from chests and now we are working on a cure for cancer. But‚ the medical period of Ancient rome and Mesopotamia were key to the advancement of medicine. The doctor patient relationship and surgery sparked something new and they helped lay a base for what we have today. Herbal remedies helped us get away from the belief that gods could cure everything. Surgery saved

results. My hypothesis was ‘as the surface-area-to-volume ratio decreases the diffusion rate increases’ my results support my hypothesis‚ because in my table of results when the surface area to volume ratio is at 14 the diffusion time is 38 seconds‚ then the ratio goes down to 9‚ and the time increases to 90 seconds. My graph also supports my hypothesis‚ because the curve on my graph slopes down which shows as the diffusion time increases the ratio decreases. One of my results that could possibly have
