Assess the likely success of a buffer stock scheme for natural rubber (25 marks) A buffer stock scheme is when the government seek to stabilise the market price of agricultural products e.g. purchasing supplies when the harvests are plentiful and selling stock when supplies are low. As stated in the study‚ the price of natural rubber has increased as a result of “responding to a combination of demand and supply factors”. The introduction of this scheme can help smoothen the fluctuation in prices

SUPPLEMENTARY MATERIAL I Unit V: States of Matter 5.7 KINETIC ENERGY AND MOLECULAR SPEEDS Molecules of gases remain in continuous motion. While moving they collide with each other and with the walls of the container. This results in change of their speed and redistribution of energy. So the speed and energy of all the molecules of the gas at any instant are not the same. Thus‚ we can obtain only average value of speed of molecules. If there are n number of molecules in a sample and their individual

percentage (%) solutions and molar (M) solutions. We also have to understand osmotic concepts. Last but not least‚ we have to know about acid-base balance. pH‚ acid and bases‚ and buffer system. Acid is substance that dissociates into hydrogen ions (H+). Base is a substance that dissociates into hydroxyl ions (H-). Buffer is a solutions containing substance that have the ability to minimize change in the pH when an acid or base was added into it. Acid and base balance in human body is essential for

Background Information Part 1 In the first part of the enzyme lab‚ we mixed a substrate and an indicator with an enzyme. There was also a neutral buffer in each of the chemical mixtures. The neutral buffer regulated the pH to around 7. We got a color palette and once we mixed each together‚ we observed and saw a change in the color of the substance. The darker and more brown the substance got‚ the more oxygen produced by the reaction. Our results showed that amount of oxygen produced increased

and are not intended to represent an entire species history. METHODS: Isolation of Fish Protein using Lamelli Buffer Before starting anything we labeled 1.5 ml flip-top microtubes and screw top microtubes 1 through 8 for each fish sample that is being prepared for electrophoresis. Lamelli sample buffer is added to each flip-top microtube in 250 µl increments; this buffer is used to denature the fish protein. Our fish protein will come from eight different fish muscle samples that are cut

There is no need to introduce Toni Morrison‚ she has world fame. Her works and accomplishments are her introduction itself. She is a path breaking Afro-American writer. Her writing engages a wide variety of readers in compelling themes that turns around community‚ racial discrepancy‚ sexual harassment‚ love‚ equality‚ incest etc. She is the voice of downtrodden Black woman. She does not take issues and themes from all over the world‚ but she writes on the crucial issues of her people and universalized

Dependent Variable: ➢ The amount of foam formed in the test tube (ml). Control Variables: ➢ The amount of distilled water and buffer of different pHs. ➢ Temperature of water bath at 25 oC : Differing temperature affects the rate of activity of an enzyme. ➢ Test tube: Using the same type of test tube for all

NA can be extracted from cells by a simple technique with household chemicals‚ enabling us to see strands of DNA with the naked eye. In this lab‚ we added a buffer solution composed of salt‚ clear dish detergent‚ and deionized water for procedure 1( the strawberry part). For procedure 2( our cheek cells)‚ we used the same buffer solution but added red food coloring so we can distinguish the DNA from the rest of the cellular components because it was all a white mixture. Finally‚ ethanol
