Science Practices: Analyzing & Interpreting Data
Analyze the data provided below to answer the following NC EOG-style questions.
Scenario 1: Enzyme Efficiency
A student team investigated how temperature affects the rate of a chemical reaction catalyzed by an enzyme. They recorded their results in the graph below.
Reaction Rate (mg/sec)
Temperature (°C)
01020304050
1. Which statement is the BEST conclusion based on the patterns in the data?
A
As the temperature increases, the reaction rate increases indefinitely.
B
The enzyme works most efficiently at a temperature of approximately 25°C.
C
Temperatures above 40°C cause the enzyme to stop functioning entirely.
D
The reaction rate is unaffected by temperature changes between 0°C and 20°C.
Scenario 2: Stream Health Investigation
A biologist collected water samples from the French Broad River to measure dissolved oxygen levels. The table below shows her findings.
| Sample Site | Water Temp (°C) | Dissolved Oxygen (mg/L) | Macroinvertebrate Count |
|---|
| Site A | 12 | 10.5 | 142 |
| Site B | 18 | 8.2 | 98 |
| Site C | 24 | 6.4 | 55 |
| Site D | 28 | 5.1 | 31 |
2. Based on the evidence in the table, evaluate the following claim:
"Warming stream temperatures caused by climate change will likely lead to an increase in biodiversity."
A
The claim is supported because higher temperatures speed up biological processes.
B
The claim is supported because oxygen levels increase as water gets warmer.
C
The claim is refuted because oxygen levels and macroinvertebrate counts decrease as water temperature rises.
D
The claim is refuted because Site A has the highest temperature but the lowest oxygen levels.
3. Describe the relationship (pattern) between water temperature and dissolved oxygen as shown in the table.
