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

Diffusion and Osmosis Lab Introduction • What molecules can pass through a semi-permeable membrane? In this lab study we tested carbohydrates such as starch and glucose‚ as well as solutions like Benedict’s and Lugol’s to see if they would cross the membrane of a cell but since we can’t actually see that happen we used dialysis tubing (acts as the cell membrane). • My prediction was that glucose and Benedict’s could pass the semi-permeable membrane but starch and Lugol’s wouldn’t be able to

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

The Innovation of the Segway By Mona Alsheddi Kettering University Jan 26th‚ 2011 1. Abstract This paper discusses the innovation of the new personal transporter: Segway. It gives a brief description of the Segway is a self-balancing electric vehicle invented by Dean Kamen and produced by Segway Inc. in 2001. The name Segway came from an Italian word means “follows”. (1) As any other transportation device‚ Segway is used to move from one place to another‚ yet it used to move among places that

to tools and machines. According to Sen(1999)‚ technology is‚ “the means or activity by which human beings seek to change or manipulate their environment.” Over a long period of time the history of technology inevitably highlights the moments of innovation that show this cumulative quality as some societies advance‚ stage by stage‚ from comparatively primitive to more sophisticated techniques. Technology refers both to the artefacts created by humans such as machines and the methods used to produce

My First Lab Report: Diffusion and Osmosis To begin‚ this is my first time doing an experiment and a lab report for biology’s class. Although‚ it was a little hard at the beginning‚ my team and I got the hang of it and we finished it on time. It was actually kind of fun. There were three steps in the experiment: 3.1 A – Molecular Movement: In this session‚ I was observing a sample and determining if there was a movement or not. 3.1B –Diffusion through semi-permeable membrane dialysis tube: In this

Its innovative product “Walk-Man” changes the way that people used to listen the music. In other word Sony brings the music system from the room to the road. But after the invention of MP3 formats‚ the bulk and the electromechanical Sony player losses its grip in the market.

Diffusion through a Membrane Introduction Molecules are constantly moving. They move in straight lines unless they are deflected by other molecules or obstacles in their environment. Diffusion is the process by which the collisions between molecules cause them to continually spread apart from each other. Their movement can be described as movement from an area of greater concentration to an area of lower concentration. Diffusion continues until the molecules are equally distributed
