1. The clinical formula of Equal was not metabolized because it has no sugar. Splenda is actually derived from sugar so the results would be different. 2. Carbon Dioxide was the gas that was produced. Two methods would be by examining the bottom of the tube and to measure the net difference. 3. The rise and change in the measurements the same way that yeast rises when baking with sugar. 4. If the yeasts metabolism was slowed down, the product would stop rising. This could be done by using the variables, light and temperature. Both of these variables would affect the product from rising. 5.
Time could have erred and the placement of the tubes into each other. If different tubes were used that fitted closer together would have improved this project.

The decrease in the blue solution was evidence. When seeds germinate they need oxygen to grow. 2. The rate of respiration was greater in the kidney beans because they were larger and absorbed more oxygen.
Climate change is simply define as change in global weather condition such as temperature, pressure etc. Climate change is a change in statistical distribution of weather pattern over time ranging from decades to millions of years. It may be change in weather conditions or distribution of weather around the average condition. Climate change is caused by factors such as oceanic process (e.g. ...
3. The rate of respiration would have been lower because more oxygen is utilized at room temperature versus a lower temperature. 4. Bromothymol blue has an indicator in it that reacts to a chemical being acidic or base. 5. The controls are the blue solution, beans and whether they are soaked or not. They eliminate the variables of heat, light and moisture. The controls are important because it gives us sound data. 6. Yes because CO2 is released out of our bodies by breathing. 7. The beans of the higher temperature would grow faster because of the increase in 02.
