AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

What factors might contribute to a low or high growth rates in a country? There are three categories of factors that contribute to a low or high growth rates. These categories are the demand factor‚ the efficiency factor‚ and supply factors. Government spending or exports can lead to a higher to aggregate demand and higher economic growth. “Economic growth requires increases in total spending to realize the output gain made available by increased production capacity” (McConnell‚ 2012‚ p. 513)

Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the

Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given by (2)

#Discuss the methods of measuring “National Income”. Ans: ‘National Income’ means the total value of goods and services produced annually in a country.There are three alternative methods of measuring national income.They are as follows: 1. Production Method 2. Income Method 3. Expenditure Method These methods are discussed billow: 1. Production Method: In production method national income is a total monetary value of all final goods and services during a
