Diffusion of responsibility is a pervasive socio-psychological phenomenon that is deeply entrenched in all societies. This tends to occur when the size of a group reaches a certain threshold and individuals within the group assume that others will take action or have already intervened‚ commonly resulting in the collective inaction by potential helpers. Another contributing factor is the gender of the individual in need for help which affects the action/inaction of the individuals in the group. The

THE EFFECT OF THE WATER CONCENTRATION GRADIENT ON THE RATE OF OSMOSIS Investigation Folio: Summative Stage 1 Biology: SEMESTER 1 2014 MARCIA SHAW - 151003X INTRODUCTION Diffusion: is when something spreads more widely from a higher concentration gradient to a lower concentration gradient. Diffusion is the process from which molecules‚ atoms or ions mingle together and move from an area of high concentration to an area of low concentration as a result to their kinetic energy. for example

Japan Essay-Ishan Mann 8.1 The Land of The Rising Sun a.k.a Japan. Japan had a past of isolation and Japan was isolated in geography because they were an island. You might ask how did Japan move through isolation economically‚ socially‚ and Politically ? Why did no one question the Emperor on the choices he made politically ? How did Japan use a currency to trade and keep things organized in their economy? How did they keep everyone social in Japan while being isolated? This essay is about then

Cell Size: Is Bigger Better? Problem: Why are cells small? Objective: To see the relationship between cell size and diffusion of materials. Hypothesis: If we cut three different sizes of cells‚ then the smallest one will survive the longest due to its sufficient permeable membrane.

Passive transport does not require energy it is powered by the concentration gradient of the molecule. Examples of passive transport are diffusion‚ facilitated diffusion‚ filtration‚ and osmosis.

1.0 Introduction 1.1 Aim and Assumptions: The aim of this experiment is to observe the rate of diffusion of diethyl ether vapour into stagnant air‚ and then determine the diffusivity. An error analysis of this calculation also had to be carried out. The following assumptions made were: * Diethyl Ether is an ideal gas * Partial pressure at the top of the tube was equal to zero * Mass transfer resistance between the liquid surface at the bottom of the tube is insufficient‚ compared with the
