Alexander The Great? A leader‚ a god‚ powerful‚ strong‚ cunning‚ and great; Alexander of Macedonia was all the above‚ but is he influential to the current day‚ evolving culture? Alexander was at his peak in conquest over 2000 years ago‚ so does he really still hold an impact to life and culture today? Controversy has followed these questions and many ideas have surfaced defending the belief that culturally Alexander was not that great. Alexander was deemed great because he conquered territories

You may be wondering what diffusion‚ tonicity‚ osmosis and semipermeable membrane is. I’ll start off by explaining semipermeable membrane. A semipermeable membrane relates to the dialysis lab #1 because in dialysis tubing is considered semipermeable barriers. Semipermeable membrane is a membrane that allows passage of some particles but not others. (Lab manual) Diffusion on the other hand‚ is a form of passive transport where particles move down their concentration gradient from a region of high

The Perfect Storm The reoccurring theme of alcohol in A Raisin in the Sun manifests itself in Walter’s mind and he becomes metaphorically drunk‚ resulting in a clouded consciousness and a distorted reality of what his family stands for and what is truly best for them. Along the way he will do anything to achieve his goal and even guilt’s his mother into becoming an enabler to his new found addiction. The progression of this impairment deepens in the same way an alcoholic’s would until Walter hits

Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

membrane OBJECTIVES: To investigate the effect of concentration of blackcurrant squash on osmosis in chipped potatoes. INTRODUCTION: In biology‚ osmosis is defined as the diffusion of solvent molecules (usually water molecules) across a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration. Osmosis is of great importance in biological processes where the solvent is water. The transport

Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially

Barrett Bleeden Period 2 Hope for the Future When the curtain falls and Lorraine Hansberry’s play‚ A Raisin in the Sun comes to an end‚ do the Youngers‚ moving into an all white neighborhood‚ have a glimmer of hope in their future? For many years‚ even before the story begins‚ the Youngers seem to know what their future was going to consist of: working for the white man and cleaning their apartment that is constantly encumbered in filth. This drab thought of this family’s existence

Diffusion & Osmosis 9/16/14-9/19/14; Jessica Bullock‚ Andrew Buchholz‚ Kristamae Masiclat TITLE: Different Ways to Express Diffusion and Osmosis INTRODUCTION: Diffusion is the spontaneous movement of a substance down its concentration gradient‚ from a region where it is more concentrated to a region where it is less concentrated. Osmosis is the diffusion of water across a selectively permeable membrane. The objective of this lab is to observe the different effects of diffusion and osmosis through
