AP Biology 11 February 2014 Observing and Analyzing the Rate of Cellular Respiration in Germinating and Non-germinating Black-eyed Peas I. Hypothesis If the cellular respiration rate of germinating black-eyed peas and non-germinating black-eyed peas is compared then the germinating black-eyed peas will have the higher respiration rate. II. Background Organisms need some sort of energy to facilitate their growth and development. Usually‚ this energy is in the form of adenosine triphosphate

Before completing the lab I had the question whether which germinated or non germinated pea would consume more oxygen and from that question I made the hypothesis that if the garden pea has more water saturated in it than the other dry peas it would consume more oxygen because water is a key molecule in the facilitation of certain reaction and processes especially in cellular respiration. In conclusion‚ the lab demonstrated many critical things relating to cellular respiration. It showed that the

2. Three controls used in this lab are the temperatures of the water baths‚ the amount of KOH added to the vials‚ and the time intervals in which we recorded rates of oxygen consumption. 3. The water initially moved into the respirometer because we had to fully submerge the respirometer. I don’t think we could have avoided some water getting inside the graduated pipet. 4. The role of KOH is to prevent the release of CO2‚ but K2CO3 we see at the bottom of the respirometers. Without CO2

This is my longer analysis of the Kingdom of Heaven. Appreciate any feedback. [SPOILER WARNING] The Kingdom of Heaven is an anti-religion humanist epic. The moral of the story is that humanism is better than religion. KOH uses a traditional storytelling formula designed to convince people to reject a particular belief or worldview. A sympathetic hero begins the story believing in the worldview the screenwriter wants to discredit. After seeing the worldview for what it really is (according to the
