Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

different preventive measures & engaged in joint projects to lower their suicide rates. Countries like China‚ Japan‚ Singapore‚ Australia & Pakistan have joined the project‚ Strategies to Prevent Suicide (STOPS)‚ in order to lessen their 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

Low Interest Rates Long Term Effect "The prolonged low-interest rate environment is transforming the banking industry from savings and loans to service and loans‚" said Dan Geller‚ executive vice president of research firm Market Rates Insight in San Anselmo‚ Calif. (Fitzpatrick) Consumers may think that the continued low interest rates are a profound thing‚ but banks on the other hand think much differently. Consumers are refinancing their houses at rates as low as 2.875%‚ while big banks like

The Effect of Varying Molecular Weights on the Rate of Diffusion of Substances August 22‚2012 ABSTRACT The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused

EUROPEAN UNIVERSITY THE EFFECT OF THE GOVERNMENT HEALTH EXPENDITURES ON MORTALITY RATE. Submitted to: Dr. Peter Mihalyi Submitted by: Narmina Rustamova Abstract. In this paper I analyze the impact of the government healthcare expenditures‚ as a percentage of gross domestic product‚ on mortality rate per 1000 population in the age group of 15-60. In order to make the estimation results more specific I add the employment rate of females to the initial regression

ABSTRACT The effect of molecular weight on the rate of diffusion was measured using two tests namely: the glass tube test and the agar-water test. The set-up of the glass tube test used two cotton balls of the same size. One cotton ball is moistened with hydrochloric acid (HCl) and the other one is moistened with ammonium hydroxide (NH4OH). The two cotton balls were inserted in both ends of the glass tube. NH4OH which has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

In my investigation I am going to establish the effect of changing light intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending
