PROCEDURE: Part A (Effect of temperature on growth) 1) 15 tubes of glucose broth are provided and one set of 3 tubes are inoculated with each of the following cultures; Escherichia coli‚ Pseudomonas fluorescens‚ Micrococcus luteus and Saccharomyces cerevisiae. The last served as control. 2) One of the three tube of each culture is incubated at each of the following temperature: * 4°C * 37°C * 55°C 3) All the tubes are incubated within 5 minutes after inoculating.

The Aim of this practical was to observe what effect temperature had on the permeability of the cell membrane. Introduction Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane)‚ however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability of the cell membranes (i.e. Tonoplast)

America’s Great Potato Baron Eric Schlosser’s biography “Fast Food Nation: Why the Fries Taste Good” explains how this invention started out of a simple potato by a man named John R. Simplot who was raised on a farm‚ un-educated and by his own account‚ left home at a young age. According to Eric Schlosser’s claim‚ “John Richard Simplot‚ America’s great potato baron‚ whose seemingly inexhaustible energy and willingness to take risk built an empire base on French fries” (Schlosser par. 2).

Lab One – Diffusion and Osmosis SECTION ONE: Methods Lab 1 – Diffusion and Osmosis can be broken down into four parts (A‚ B‚ C‚ and D). Lab 1A – Diffusion In this exercise‚ we tested diffusion through dialysis tubing. This was done through a demo with the teacher‚ rather than individually in groups. First‚ a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was

The results provide evidence that when there was an increase in the sodium chloride concentration the mass of the potato prisms declined. At the zero percent concentration there was an increase of mass by 1.75%‚ from there the 1%‚ 3%‚ 5% and 10% begun on a downward trend with the percentage change in mass declining. The graph was on a steady decline from 0% being the highest point with a change of mass of 1.75% finishing with the 10% solution on a decline of -12.28%. From observing the scatter plot

TOY: MR. POTATO HEAD! Since the time of my childhood I have been exposed to hundreds of toys and games. However‚ only a few stand out in my memory and even fewer still remain in my possession today. There are many toys in America‚ which are known by all ages‚ nationalities‚ and social classes. Toys such as Barbie‚ Legos‚ Cabbage Patch Kids‚ GI Joe‚ and many more are well known commodities‚ which have been in existence since before my time. Although there are numerous toys I can remember

treated potatoes." In short‚ it’s a potato powered battery‚ and it’s as real as you’re hoping it is. The simple‚ sustainable‚ robust device can potentially provide an immediate inexpensive solution to electricity needs in parts of the world lacking electrical infrastructure‚ but we’re hoping that it can work a similar amount of magic for developed nations as well. Researchers at the Hebrew University discovered that the enhanced salt bridge capability of treated potato tubers can generate electricity

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no
