- Independent variable: temperature; dependent variable: volume of carbon dioxide produced. - Stirring mixture: ensures uniform distribution of yeast and glucose, promotes consistent fermentation. - Methodology: temperature variation, measure CO2 production, control variables, replicate trials, record data. - Graph prediction: CO2 production vs. temperature, axes labeled with units, expected maximum rate identified. - Crabtree effect: comparison of S. cerevisiae and C. tropicalis, evidence of fermentation behavior under high glucose and oxygen conditions. - Species diversity analysis: correlation between latitude and bird species count, statistical significance, limitations of sampling method.
