Diffusion In Agar Cubes Is Bigger Better? OR Is Smaller Smarter? Adapted from Flinn Scientific Publication No. 10110 Introduction: Diffusion is one of the very important processes by which substances such as nutrients‚ water‚ oxygen‚ and cellular wasted are transported between living cells and their environment. This activity will help you explore the relationship between diffusion and cell size by experimenting with model “cells.” In this experiment‚ you will use agar cubes to which the

Background information: 1) What is diffusion? Movement of a particular type of molecule from an area of high concentration to an area of low concentration. 2) How is diffusion used by living cells? Living cells bring in food‚ water and oxygen‚ and excrete wastes through the process of diffusion 3) List two body systems in vertebrates that are dependent on diffusion Digestive system and respirational system 4) What is meant by the term metabolism the chemical processes that occur within a

have you pick up a cube and said damn it wish I could complete the hold thing and not just on side or finish without sticker peeling. C. In time of boredom or just a mind opener its nice to baffle your continuesly with speed trials‚ always trying to beat the time before. D. Within this informative speech I hope to open your eyes to the least complicated puzzle that was developed in the late 70’s early 80’s E. 1. Today I will give you a brief history on the cube. 2‚ Then

Figure 1. Average Mass Specific Surface Area for Three Fish. Error bars represent standard deviation from the mean. The graph represents the mass specific gill surface area for a sample size of 6 gill arches for each of the 4 lab sections (n=24). For Mackerel‚ the mass specific gill surface area was 13.62 cm2/kg. For Whiting‚ this value was 9.34 cm2/kg. Lastly‚ for flounder this value was 2.93 cm2/kg. Results: The three different species of fish‚ Mackerel‚ Whiting‚ and Flounder‚ have distinct

affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with the acid. This is because the acid only comes in contact with the particles on the surface of the donut. But‚ if you crush
