Biology lab Homework 1. Write up a hypothesis for this lab. The respirometers with only germinating peas will consume the largest amount of oxygen and will convert the largest amount of CO2 than the respirometers with beads. The temperature of the water baths directly effects the rate of oxygen consumption by the contents in the respirometers (the higher the temperature, the higher the rate of consumption). 2. Tell me what the independent variable and how this variable was manipulated. The independent variable is the temperature of water. The temperature was changed from room temperature to a colder ice bath. 3. Tell me what the dependent variable was and how this variable was measured The dependent variable is the amount of oxygen consumed. 4. Tell me what all the controlled variables were and how they were controlled. The controlled variables is the numbers of beans, timed every 5 min for all respirometers. 5. I want to see your processed data table and I want to see the graph of oxygen use for your mung beans both in the ice bath and they in regular temperature. Use corrected values. Key: respiration rate/ temperature Table 1 | ml/ 5minutes | Ml/5minutes | Ml/minutes | Ml/5 minutes | Time | Room temperature bean | Room temperature glass | Cold temperature bean | Cold temperature glass | Initial | 6.1/25 | 8.2/25 | 8.2/11 | 7.5/11 | 5 | 6/24 | 8/24 | 8/11 | 7.3/11 | 10 | 5.8/24 | 8.2/24 | 8.2/10 | 7.5/10 | 15 | 4.7/24 | 8.2/24 | 3.1/10 | 4.9/10 | 20 | 4.3/24 | 8/24 | 3/10 | 5/10 | 25 | 3.1/24 | 7.9/24 | 2.9/10 | 5.1/10 | 30 | 2/24 | 7.8/24 | 2.9/10 | 5.4/10 | Table 2 | ml/ 5minutes | Ml/5minutes | Ml/minutes | Ml/5 minutes | Time | Room temperature bean | Room temperature glass | Cold temperature bean | Cold temperature glass | Initial | 3.9/25 | 1.8/25 | 1.8/11 | 2.5/11 | 5 | 4/24 | 2/24 | 2/11
