DIFFUSION AND OSMOSIS: WHAT’S TO EXPECT? Diffusion and osmosis are very important in biological process. Diffusion is the movement of molecules or ions from a region of their high concentration to a region of their low concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane. To gain a better understanding of diffusion and osmosis‚ we examine multiple experiments to show diffusion and osmosis in animal cell‚ plant cell and synthetic cell. In our first experiment

1. Describe the difference between an analog signal and a digital signal? Analog signal has a smooth consistency over a vary of time. An example of analog signal is voice. Digital signal is smooth‚ but after a period of time‚ it will change its consistency. An example of digital signal is text. 2. What is the function of a dial up modem? A dial up modem‚ modulates the digital data received from a computer‚ and transfers it into an analog signal‚ which then transmits down a telephone line. The

Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells

Week ONE: Introduction to information technology and society; WEB 1.0 v 2.0 v3.0 WEB 1.0 When web was in its early days; people didn’t know what to show on the computer screen Static web – it was a search for online viability. WEB 2.0 When we got a grip of the technical part‚ the real possibilities of the web became clear Discovered the power of networks – power of links‚ collaboration‚ content and research‚ friends. Technical aspect of the web didn’t change as much‚ web 2.0 was more of a

Experiment #1 Date: September 13‚ 2011 Title: Diffusion in Gases I Aim: To observe the diffusion of bromine Apparatus and Materials: Glass tube‚ bromine‚ fume chamber Diagram: Procedure: -Liquid bromine was placed in a jar and covered Observations: When first placed in the jar the original color of bromine was red-brown. As it began to diffuse its color changed from dark brown to a lighter brown until it becomes a yellow-like orange color. As it was diffusing liquid bromine changes its state

Cultural Diffusion and its Influence on Europe and Sub Saharan Africa Both Europe and Sub Saharan Africa was and still is a melting pot consisted of a blend of races and cultures that has integrated into a cohesive whole. Take The Melting Pot restaurant as an example; The rich blend of the chocolate sauces can resemble a specific culture such as strawberry‚ white‚ dark‚ raspberry‚ etcetera‚ but when they are mixed together‚ the melting pot creates a swirl that symbolizes the blending of one culture

Effect of Temperature on Salt Diffusion Rates and it’s Relation to the Human Body Hypothesis: Ordinary table salt is known to dissolve easily in water. Dissolving or diffusion is the spreading of particles in another substance. This is seen when smoke from a chimney diffuses in the air around it‚ or when dropping coloring in water. When NaCl‚ sodium chloride‚ or otherwise known as ordinary table salt is combined with water the separate salt and water molecules will be attracted to each other
