Slide One- Which areas did Vesuvius hit? Vesuvius entered the history of volcanology with the eruption of 79 AD burying towns and making history as one of the most fascinating natural disasters ever to hit this planet. The eruption destroyed the cities of Pompeii‚ Herculaneum‚ Oplonti and Stabiae and caused the death of thousands of people‚ including Pliny the Elder. Earthquakes occurred frequently before the eruption in 79 AD but the locals disregarded them‚ as they were extremely common in this

Using dialysis tubing to model diffusion of a cell membrane and investigating the influence of solute concentration on osmosis Purpose * Discover how dialysis tubing diffuses the cell membrane * Explore the effect of solute concentration on osmosis Background A cell membrane is a very significant function in the human body. In one sense‚ it is used as a barrier to keep the enzymes‚ DNA‚ and metabolic pathways that bundles everything together. Cell membranes are also used as a gateway

CONSERVATION OF MOMENTUM PRACTICAL WRITE UP AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system. HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction. METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was

Case Study on Nike Inc. What is the WACC and why is it important to estimate a firm’s cost of capital? The WACC is a firm’s overall cost of capital‚ taking into account the weighted average of its equity and debt costs of capital. A firm’s WACC is the minimum return (hurdle rate) required by its capital providers to stay invested. Therefore managers of a firm should only invest in projects that generate returns exceeding the firm’s cost of capital. For the company’s owners the WACC is the minimum

AT1- Osmosis In Potatoes Aim: Investigate the movement of osmosis through a selectively permeable membrane‚ in this case potato. Introduction: Osmosis is the movement of water through a semi permeable membrane‚ separating solutions of different concentrations. The water passes from a region of high concentration to a region of low concentration‚ until the two concentrations are equal in concentrations of water. Many cell membranes behave as semi permeable membranes‚ and osmosis is

Investigate osmosis between potato tissue and sugar solutions. Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato core of a given size 10mm Hypothesis: Osmosis is defined as the net movement of water or any other solutions molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable

The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

HOW TO WRITE AN UNKNOWN LAB REPORT IN MICROBIOLOGY GENERAL Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing. The results of the exercise or experiment are what are being showcased‚ not the writing. The purpose of scientific writing is not to entertain‚ but to inform. The writing should be simple and easy to understand. There is a specific style that must be followed when writing scientific reports.
