Written Task The downfall. The cold pouring rain had finally stopped. The man who several years ago were used to be Winston Smith was walking down the narrow street closely to his apartment in Victory Mansions. It was the year 1989‚ or at least he thought so. It has been raining for days‚ or even weeks‚ it doesn’t matter. The noise of bombs turning buildings into dust was very often in that week‚ and they were dangerously close to the part of the city where most of the party members were relocated

Math Studies: Units Project Talha Mirza 1A Gilmartin Dear noble tribe leaders of T-Island‚ I have created a brand-new system of units for us to use in our daily lives called the T-Dog system. You will find this system to be quite useful‚ as it includes six unique units which measure temperature‚ length‚ time‚ weight/mass‚ volume/displacement‚ and currency. By utilizing these units‚ life will be made easier for us. Moreover‚ if it is ever decided to switch to other well-known systems‚ it is

6.1.1 If the reaction produces heat (increases the temperature of the surroundings) then it’s exothermic. If it decreases the temp (i.e. absorbs heat) then it’s endothermic. Also‚ the yield of an equilibrium reaction which is exothermic will be increased if it occurs at low temps‚ and so for endothermic reactions at high temperatures. 6.1.2 Exothermic : A reaction which produces heat. Endothermic : A reaction which absorbs heat. Enthalpy of reaction : The change in internal energy (H) through

ROLE OF NEUROTRANSMITTERS IN LEARNING AND MEMORY – Martinez and Kesner (1991) Aim: determining the role of the neurotransmitter acetylcholine on memory Method: * Rats were trained to go through a maze and get to the end‚ where they received food * Researcher injected one group of rats with scopolamine (blocks acetylcholine receptor sites thus decreasing available acetylcholine) * Injected second group of rats with physostigmine (blocks the production of cholinesterase – cholinesterase

I’m not one who usually backs down from a challenge. However‚ deciding to take the full IB diploma was different. I wanted to challenge myself academically‚ but many thought I could not handle it. For example‚ my adviser warned me that the IB program was extremely rigorous and he was concerned I would struggle. My parents were also worried that I’d spread myself too thin with school and other activities including clubs and sports. I could either take the easy way out‚ or embrace the challenge of
