The Effect of Different Molar Mass on the Diffusion on Substances Lunar-maius A. Gaerlan Group 2 Sec. X – 9l August 15‚ 2012 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using agar-water gel test. The agar-water gel set up was composed of a petri dish of agar-water gel containing three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate (K2Cr2O7) and methylene blue(C16H18N3SCl) were simultaneously introduced to each well. Methylene blue

structure of the plasma membrane and explain the process of active and passive transport through the membrane. The plasma membrane is made up of proteins that form pores and channels‚ carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane is a double layer

12 Mar 2012 Technological Diffusion During the European Renaissance The innovations discussed here represent revolutions in warfare‚ society‚ and art that saw a rapid diffusion through the societies of Europe during the renaissance for varying reasons. Whether for survival‚ economic gain‚ or aesthetic pleasure they were eventually embraced throughout Europe laying down some of the bedrock that modern western society would be built on. The spread of firearms throughout renaissance Europe had

In the article “Artificial Stupidity” linguist Geoffrey Pullum states his opinions on artificial intelligence and how his every day interactions with simple technology affect his opinions on this. He starts his article by reciting a log of the redundancies of specific user-interfaces that he encounters throughout a five day period. Most of these interactions are with simple appliances such as a projector giving a notification that it will go to standby mode in “one minutes” or a self-checkout machine

Quest 1-2: Describe the fluid mosaic model of plasma membrane structure and list the major components of the membrane. How did scientists discover that the membrane was “fluid”? Explain one experiment that we discussed. • The fluid mosaic model of plasma membrane was the idea that lipids or proteins could move in the membrane laterally. The plasma membrane is made up of a phospholipid bilayer and controls a lot of what goes in and out of the membrane by the organelles from within. The bilayer is considered

Artificial Turf: A Dangerous Playing Surface Some of the changes that have occurred in professional football were necessary for the game. Pads‚ helmets and other protective equipment helped the players safety. Other developments though‚ especially artificial turf‚ have proven themselves detrimental to the game and its participants. Just as changes were made earlier‚ they must be made again. Stadiums need to convert back to grass playing fields for the safety of football players‚ the satisfaction

Kunal Pathade 11/10/13 10-6 WHAP Hebrew Essay: Continuity and Cultural Diffusion The Jews lived to preserve their culture; that essentially represented the fundamental goal of life to the Jews. The Jews observed the decadence of the Sumerians as a cause of cultural diffusion‚ and wanted to make sure that same thing would not happen to them. Eventually‚ the Jews did become vulnerable to cultural diffusion around the 4th century CE when the Greek-Macedonians from the West came; the great and

Artificial intelligence or Al for short capability of a computer to perform functions that is normally associated with human intelligence‚ such as reasoning‚ learning or self-improvement. Its concept requests a lot more than present information to the user; it requires that the machine is not only able to store and manipulate information but also to deal with its "meaning". AI is what we call understanding‚ a combination of computer science‚ physiology and philosophy. The element that the fields
