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)

Title: Studying the Effect of types of Food on a Betta Fish’s growth Introduction: Before you consider buying an animal or pet for the first time‚ you should probably to some research on that animal as we did. It’s very important to know what they eat‚ their environment‚ and also what you shouldn’t do for the health and safety of your fish. For instance‚ our fish cannot eat regular goldfish food. We wanted to test out how the types of food effect the growth. As a control‚ we went for something

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

increasing number of suicide. However‚ in trying to prevent the increase in number of suicide deaths and attempts‚ one must know what the leading causes of it are. Suicide rates change over time‚ and the factors influencing them remain poorly understood. Economic factors‚ in particular unemployment & income growth‚ have been suggested as a major influence. History would tell us that economic factors really affect suicide rates. From 1928 to 2007‚ suicide rates has risen and fallen in tandem with the

Effect of Temperature on Cricket Respiration Crickets are ectotherms that rely on their environment as a source of heat for their metabolism. Warmer temperatures allow crickets to respire at a greater rate.

countries produce more than is absorbed by their domestic economy so they export the surpluses. Either of these actions means that a nation is going to have a trade deficit or a trade surplus. Thus‚ this work is done to examine and find out how the growth of National Income can be affected by trade balance. STATEMENT OF PROBLEM Every country wants to be just an exporter of goods and services. But since no man is an island‚ no matter how much exports a country makes‚ it still has to import at some

The Effect of different soil types on plant growth Introduction Australian Gardeners are continually looking for better and cheaper options to improve the growth in their gardens. In Chinchilla‚ it is common to see rich vibrant coloured loam‚ but this is not suited to all plants. Common gardeners will find that it is important to understand what soil type they are on and how the climate conditions that surround the area may affect the growth of the plants they wish to establish‚ which contributes
