Ms. Green's biology students were studying cellular respiration. One simple organism, yeast, can be used to test the rate of fermentation using different variables. Each group mixed 2 grams of yeast with warm water and placed the mixture into one of five test tubes. The variables can be seen on the graph of student data. Test tube five held only yeast and warm water. The groups used the height of the carbon dioxide bubbles produced in a test tube to determine which group had the highest rate of fermentation.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

idk

explanation:

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
