How does diffusion affect the rate of growth? If I placed a gummy bear in various solutions‚ then the gummy bear would change in size‚ because diffusion and osmosis cause the gummy bear to react to the solution’s molecules‚ and further affects the gummy bear’s mass. An experimental lab conducted in class was tested‚ essentially to observe the effects of diffusion/osmosis. More specifically‚ according to‚ “merriam-webster.com/dictionary/diffusion‚” the process of diffusion causes particles to spread

One purpose of the experiment was to gain an understanding of diffusion and osmosis‚ specifically in context of a plant or animal cell reaction to an isotonic‚ hypotonic‚ or hypertonic solution. Another objective was to understand the nuances of simple diffusion‚ facilitated diffusion‚ and active transport and to explicate the characteristics affecting the rates of diffusion. The next objective was to be able to explicate the partition coefficient and its influence on hemolysis. The final objective

spread faster‚ because the particle in the hot water have more kinetic energy than the cold water‚ so it will spread faster. Particles at a higher temperature are moving faster than particles at a lower temperature‚ that is one of the law in particle theory. It spread slower in cold water‚ because the particles is moving slower than the hot water‚ when the water cool down the particles start to lost kinetic energy and they slowly clump together and vibrate. Procedure: First gather all the materials we

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

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
