Her teacher suggested that she redraw her graph as a line graph. Why should she redraw the graph?
**Title: Measuring the Respiration Rate of Yeast Through Carbon Dioxide Production** Anjuli conducted an experiment to determine the respiration rate of yeast. She measured this by assessing the amount of carbon dioxide (CO₂) produced over time. The resulting data was plotted in the graph shown below. **Graph Explanation** **Rate of Carbon Dioxide Production in Yeast** - **Y-Axis (Vertical Axis)**: Represents the amount of Carbon Dioxide (CO₂) produced, measured in milliliters (mL). The values range from 0 to 16 mL. - **X-Axis (Horizontal Axis)**: Represents Time in minutes (min). It is divided into five time points: 1, 2, 3, 4, and 5 minutes. **Data Points:** - **At 1 minute**: The amount of CO₂ produced is approximately 2 mL. - **At 2 minutes**: The amount of CO₂ produced is approximately 0 mL. - **At 3 minutes**: The amount of CO₂ produced is approximately 2 mL. - **At 4 minutes**: The amount of CO₂ produced is approximately 12 mL. - **At 5 minutes**: The amount of CO₂ produced is approximately 15 mL. **Conclusion:** The graph illustrates that the respiration rate of yeast, indicated by the amount of CO₂ produced, increases over time, with a notable surge starting from the 3rd minute onwards. This experiment highlights the dynamics of yeast metabolism under the conditions provided. This content helps in understanding how biological experiments can be used to measure and graphically represent metabolic processes such as respiration in microorganisms like yeast.

**Understanding Different Graph Types: A Line Graph Versus a Bar Graph** **Scenario:** A student has presented a bar graph that depicts the amount of carbon dioxide over time, measured in minutes. Her teacher suggested that she redraw her graph as a line graph. Let's understand why this change is recommended by examining the details and implications of both graph types. **Current Graph:** The bar graph currently used plots: - **Y-axis:** Carbon Dioxide (unknown units) - **X-axis:** Time (minutes), spanning from 1 to 5 minutes - Bars are drawn for each minute mark, showing varying levels of carbon dioxide. **Teacher's Suggestion:** The teacher suggested the student redraw her graph as a line graph for the following reasons: A) **A line graph looks better in a scientific report.** B) **She was measuring a rate of change.** C) **She had graphed the wrong relationship.** D) **Her experiment had many different variables.** **Educational Analysis:** 1. **Visual Representation in Scientific Reports:** - Line graphs are often preferred in scientific reports for data that changes over time as they clearly show trends and patterns. This helps in emphasizing the continuity of data points, which is crucial for understanding trends. 2. **Measuring Rate of Change:** - Since the student measured carbon dioxide levels over time, a line graph would be more appropriate to show how carbon dioxide levels change from one minute to the next. Line graphs are ideal for depicting rates of change, making trends easier to analyze. 3. **Correct Relationship:** - It's important to graph the correct type of relationship. Bar graphs are typically used for categorical data, while line graphs are used for continuous data, such as time measurements. 4. **Multiple Variables:** - This point is less relevant if the student's experiment was measuring a single variable (carbon dioxide) over time. The key issue here seems to be how best to visualize that single variable's change over time. **Conclusion:** The recommendation to switch to a line graph is primarily due to its effectiveness in showing changes over time (option B) and its appropriateness for the type of data collected (continuous measurement of carbon dioxide levels over time). **Next Steps:** - **Save and Exit:** Save your current work and proceed to the next section. - **Mark this and Return:** You can mark this question for review and return to it later for
