Effec | Effect of caffeine on plant growth | Description This science fair project was performed to find out the effect on plant growth of adding caffeine to the soil. The experiment was done by using mung bean plants and watering them daily with water‚ water mixed with caffeine and with a coffee mixture. Hypothesis The mung beans watered using the coffee mixture will grow the fastest. Overview Caffeine and plant growth The effect of adding caffeine to the soil and its effect on plant

Japan has the oldest life expectancy in the world. That means people in Japan live a really really long time. Men live to 79 years old. Women live a little over 86 years old. What in the world causes Japanese people to live so long? After WWII‚ Japan had one of the lowest life expectancies in the world‚ which suggests it’s not genetics that keeps them alive for so long (the guy in the picture above just turned 113). It’s not even that Japanese people visit doctors 12+ times a year. The answer is

prospects not often remarked upon is that their population is aging. By 2025‚ the share of the elderly in the population of Singapore‚ Hong Kong‚ Taiwan‚ Japan and South Korea will at least doublem and the share of the young will fall sharply. The ageing of the population will drag down the potential rate of growth as a result of the fall in volume of labor input and the decline of the domestic saving rate. Furthermore‚ it will also serve as negative effects upon fiscal conditions and households through

Title : THE EFFECT OF PH ON THE ACTIVITY OF CATALASE Aim : To study the effect of pH on the activity of catalase. Introduction : Catalase‚ an enzyme found in many different tissues‚ catalyses the breakdown of hydrogen peroxide into water and oxygen. 2 H202 → 2H20 + O2 Hydrogen peroxide is a toxic substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by finding the rate of oxygen release from hydrogen peroxide

Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function

2. THEORY OF DEMAND AND SUPPLY: THEORY OF DEMAND: Demand refers to the quantity of a product that consumers are willing and able to buy at a particular price and over a given period of time. The law of demand states that more is bought at a lower price than at a higher price. In other words‚ the law of demand postulates an inverse relationship between the price and quantity demanded of a commodity‚ all other factors affecting demand remain constant (ceteris paribus). A market demand curve

Investigating the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed
