Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease. Equipment • Eye protection • 250 mL beaker • Timing device • Scoopula • Ruler • Scalpel • Sodium hydroxide solution • 3 different sized cubes of phenolphthalein agar • Paper towels Purpose

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the

SEMÁNTICA Y PRAGMÁTICA I UNIT 1 What is semantics? Some linguistics link the notion of semantic to meaning‚ others to meaning in language‚ or meaning in communication through language‚ when others link it with other branches‚ like grammatical or literal meaning. What is meaning? The fact we need to have in mind is where to locate meaning‚ or parts of meaning. History of Semantics: Semantics had a central place in linguistic study from the very beginning. American structuralism banned Semantics

Biology diffusion Science ISA To find out if concentration affects the rate of diffusion. I predict that the higher the concentration of acid the faster the reaction will be. Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. Apparatus: * 1 measuring cylinder * 1 test tube * 1 stop clock * A large gelatine

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
