Salt of the Earth Flannery O ’Connor ’s novels and stories are inhabited with unique and flawed characters who are the result of O’Connor ’s satiric worldly perspective. While they are sometimes humorous‚ these misfits are usually unpleasant. Critics have termed them "grotesque‚" but O ’Connor has rejected this term because it suggests that the characters are too weird to belong in the real world. Instead‚ O ’Connor insists that the South is inhabited by many such people. For every good or evil

Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day

The Bread of Salt Summary It was his assigned duty to be up early in the morning and be on his way to the baker’s to buy rolls and pan de salt for the breakfast table. He was fourteen and he has already got used to his task. On his way he thought of the bread of salt – pan de salt – and wondered how it was made‚ what gives its flavour and shape. He looked around the landscape at daybreak and once again remembered how much he adored Aida‚ the niece of the old Spaniard whom he thought he was destined

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport‚ without requiring bulk motion. Thus‚ diffusion should not be confused with convection‚ or advections‚ which are other transport mechanisms that utilize bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach

Osmosis and Scientific Method Lab Report Abstract The purpose of the lab is to see how different size potatoes have faster water movement depending on the concentration of sucrose it was placed in. We had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the

different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears of different colours (dependent

Lab Report DIFFUSION AND THE EFFECT OF AMYLASE. Aim: We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.)
