Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

the purpose was to have found out how different chemical solutions help or harm radish plant growth when the seeds of the radish plant are soaked in said solutions prior to planting. Background: The IRP project I am doing is based off the subject of seed germination. The seeds I will be planting are cherry belle radish seeds‚ freshly bought. Instead of planting the seeds in soil like it is normally done‚ the plant seeds will be placed on paper towels to grow for better observation of the roots‚ and

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Principles of Cellular Respiration Ashley Flannigan November 5th‚ 2013 Professor Ryan BSC2010 Lab Fall 2013 2220 ABSTRACT Students in a Biology 1 lab class constructed an experiment on Cellular Respiration by investigating the effects of temperature on crickets’ metabolic rate. By following the following procedures out of the Lab Manual‚ the students were able to find an almost accurate representation of the crickets’ cellular respiration rate under various temperatures in order to

What affect does fertilizer have on the rate of growth in plants over a certain period of time? When tested‚ there is no affect on the growth of plants from a change of an environmental factor‚ such as an exposure to fertilizer. By changing the independent variable (whether or not the plant was planted with fertilizer)‚ you are testing to see how the dependent variable would change (the growth of plants). In order to assure that there is no experimental error‚ a control must be kept to produce the

function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their specific function. The life processes of nutrition and respiration are related to photosynthesis and Aerobic Cellular Respiration. All organisms use material from the outside

Done by: Instructor: Introduction Respiration is the number of processes which leads to the oxidation of organic compounds to produce the energy. There are several types of respiration‚ and one of them is aerobic. During the aerobic respiration‚ human uses the oxygen from atmosphere and produce carbon dioxide. A cardiorespiratory system which includes lungs‚ heart‚ blood vessels and others is responsible for all the processes linked to the respiration and controlled by the nervous system. During
