A comparison and contrast essay on private and public means of transport Cost * Private transportation by far is the more expensive option. The biggest cost of owning your own vehicle is the purchase price. Additionally‚ general maintenance such as oil changes‚ filling the gas tank and auto insurance are ongoing costs of owning a car. Car repairs and parking fees are also sometimes necessary. When choosing public transportation‚ you pay per ride and the fee is usually quite small‚ plus you

Lab Report on Osmosis and Diffusion Biology 1‚ Period 3 March 15‚ 2010 Lab Team: Jason Perez‚ Kicia Long‚ Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing. Materials Used 2.5 cm dialysis tubing 15% glucose

extra hydrogen bonds on top of each other‚ making extra-tough microfibrils that cannot be digested by most organisms. Proteins accomplish many different tasks‚ including structural support‚ storage‚ transport‚ movement‚ and defense against foreign substances. One noteworthy type of protein‚ called an enzyme‚ acts as a catalyst‚ speeding up chemical reactions in the cell. All proteins are composed of the same set of 20 amino acids‚ and each amino acid differs from the other only by the "R group" attached

traded in Africa. The trans-Saharan trade routes were a vast trade network that reached across the continent‚ on which diverse goods and resources were traded‚ and knowledge‚ ideas‚ and religion spread in a phenomenon known as cultural diffusion. Cultural diffusion that occurred along the trans-Saharan trade routes shaped the development of culture in medieval Africa. The trans-Saharan trade routes provided African people access to goods and resources that were not local to their

the ideas of cultural diffusion. Cultural diffusion is the exchanging and adaptation of ideas amongst people of the world. It is a constant force that allows us to accept and modify an idea to mold into our own world. Throughout great civilizations of history‚ the idea of cultural diffusion has spread and continues to spread in present time. This idea usually enforces contact between neighboring strangers. McNeill addresses the specific issue of how cultural diffusion came to shape new civilizations

Does the PH level of acids in our stomach affect the digestion proteins? Yes‚ if the acidity in my/a stomach is high in terms of the PH balance then the proteins in our stomach will be digested faster because acids are known to breakdown and eat away at many objects. The purpose of this project was to observe how the digestion of protein varies at different pH levels. This project in my eyes helps society by finding the best types of food (i.e. ones with higher/ lower acidity and pH balance)

In order to purify CelB2 protein bound to maltose-binding-protein‚ amylose affinity chromatography was performed. The amylose resin present in 20% ethanol was first diluted by adding 10 mL of 20 mM TrisHCl‚ pH 7.4‚ 0.2 M NaCl‚ 1 mM EDTA and centrifuged at 700 rpm for 5 minutes. After decanting the buffer‚ another 10 mL of TrisHCl‚ pH 7.4‚ 0.2 M NaCl‚ 1 mM EDTA was added to this resin solution and centrifuged at 700 rpm for another 5 minutes to further dilute the ethanol concentration in the resin
