Separation techniques Chromatography Chromatography is a separation technique used to separate the different components in a liquid mixture. It was introduced by a Russian Scientist Michael Tswett. Chromatography involves the sample being dissolved in a particular solvent called mobile phase. The mobile phase may be a gas or liquid. The mobile phase is then passed through another phase called stationary phase. The stationary phase may be a solid packed in a glass plate or a piece of chromatography

Changes in the functionality of the ecosystem occur when we, as humans, increasingly alter the ecosystem for our use. As we did more research into the Grass Carp issue we found that the fertilizer that farmers were using caused a high growth in water supply which was backing up the waterways. To solve this problem, Grass Carp placed in the late to control this issue. Over the course of time, we found that this invasive species (Grass Carp) began to reproduce and overpopulate the lake, causing the

Lerner and Lerner (2008) define osmosis as the movement of water across a membrane that is selectively permeable. Osmosis is important in plant cells because it plays a role in regulating guard cells, which are cells that are on the surface of a plant’s leaves and control the opening of the stoma. When the stoma is open, it increases the water movement out of the plant by a process called transpiration. When there is a shortage of water, the guard cells well get smaller and close the stomata, and the transpiration process will move slower

minimal risk procedure; however, many inhabitants residing in fracking sites have voiced various detrimental by-products produced from the fracking process. Fracking, or hydraulic fracturing, has elicited substantial concerns in health, water availability, water contamination, air pollution, land pollution, and in causing earthquakes. Still, with dated federal regulations, oil and gas companies have meticulously maneuvered fracking procedures by releasing insufficient data to the public; and, appealing

1. Heat water in a pan or beaker until the water (enough water so the object remains covered) is boiling vigorously. 2. While waiting for the water to boil, measure the mass of the metal with the scale. Remember to record the answer to one more decimal place than what is marked off by the scale. 3. Once the water, on the stove (or over a bunsen burner), is boiling, drop the metal object into the pot (or beaker) and let the object sit in the water for about ten minutes. 4. While the metal
