Mongolia Mongolia (Mongolian: Монгол улс (help·info)) is a landlocked country in East and Central Asia. It borders Russia to the north and the autonomous region of Inner Mongolia‚ China to the south‚ east and west. Ulan Bator‚ the capital and largest city‚ is home to about 45% of the population. Mongolia’s political system is a parliamentary republic. The area of what is now Mongolia has been ruled by various nomadic empires‚ including the Xiongnu‚ the Xianbei‚ the Rouran‚ the Gökturks and others

In the statistical analysis statistical formulas and techniques are used to analyze the significance of a set of data and the validity of the conclusions made based on that data. These are some terms and definitions that will be crucial to understanding the validity of this experiment. An enzyme is a protein that acts as a catalyst to lower the activation

Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

Lab 6.C Hypothesis: If enzyme activity is affected by the pH of a solution‚ then the enzymes will experience the greatest activity at a pH of 6. Variables: Independent Variables Dependent Variable Controls Four different pH values (10‚ 7‚ 6‚ and 3) Change in color of the solution The amount of potato extract‚ pH solution‚ and catechol used (1 cm +/- .1cm) Size of the test tubes Amount of time allowed for the catechol to sit with the potato extract and pH solution (20 minutes with 5

enzymatic activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases‚ the rate of enzymatic activity increases

Summary of IAS 18 Objective of IAS 18 The objective of IAS 18 is to prescribe the accounting treatment for revenue arising from certain types of transactions and events. Key Definition Revenue: the gross inflow of economic benefits (cash‚ receivables‚ other assets) arising from the ordinary operating activities of an entity (such as sales of goods‚ sales of services‚ interest‚ royalties‚ and dividends). [IAS 18.7] Measurement of Revenue Revenue should be measured at the fair value of the consideration

Enzymes are organic catalysts‚ usually proteins that speed up metabolic reactions. They lower the amount of energy needed for reactions to progress in cells. In enzymatic activity‚ the molecules at the beginning are called substrates. Lactose metabolism is when lactose is destroyed‚ maintained or produced. For instance‚ being lactose intolerance that’s where lactose is destroyed. Metal cofactors in enzyme activity are required to function properly. The Effect of Temperature on Enzymatic Activity:
