AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

November 04‚ 2012 Running Head: Turnover Rate in Corrections Abstract Throughout the years‚ there has been one major dilemma that continues to hassle the administration whose sole purpose is to provide institutional sanctions‚ treatment programs‚ and services for managing criminal offenders. This dilemma is the high turnover rate of the Corrections Officers‚ whom agencies nation wide are losing at an extremely high rate. Recent statistics indicate that nearly half of

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

representation‚ which more clearly displays the relationship‚ view Figure 2. The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%‚ the rate was 3.05 mg/dL per minute‚ and for the 25%‚ the rate was 2.76 mg/dL per minute. As seen‚ the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier‚ the Collision Theory states the rate of a chemical reaction is proportional to the number of collisions that occur

to 28 degrees the slope of the line increases and shows a slight curve. The rate of evaporation increases with temperature since transpiration is a cooling mechanism to release heat. More stomata open as temperature increases as this allows a faster transpiration rate. Although‚ at much higher temperatures‚ plants close stomata to prevent excess water loss. b. The increasing humidity causes reduced transpiration rates. This is because atmosphere is saturated with water vapor and so not much can

In this report we will explain and discuss the inflation rate that happened in Australia for the last three years. The issues uncovered will allow us to see the reasons behind the decreasing in inflation rate in Australia. Lastly we will discuss the type of inflation that will happen after the collection of carbon tax that started in the beginning of July 2012. In the table and chart below are some of statistics that we obtained from several sources to aid our explanation: 1. Euromonitor International
