Graphing Activity \#2

Base your answers to questions 1 through 5 on the information and data table below and on your knowledge of biology.

The rate of respiration of a freshwater sunfish was determined at different temperatures. The rate of respiration was determined by counting the number of times the gill covers of the fish opened and closed during 1-minute intervals at the various temperatures. Data collected:

### Step-by-Step Solution

#### Directions (1-3):
Using the information in the data table, construct a line graph on the grid provided.

1. Label the [tex]$x$[/tex]-axis and indicate the units. [1]

- The [tex]$x$[/tex]-axis represents the temperature. Therefore, the label should be "Temperature (°C)".

2. Mark an appropriate scale on each axis. [1]

- For the [tex]$x$[/tex]-axis (Temperature in °C):
- Mark points to cover the range of temperatures from 10°C to 27°C.
- For the [tex]$y$[/tex]-axis (Gill Cover Openings and Closing Per Minute):
- Mark points to cover the range from 15 to 60 gill cover openings per minute.

3. Plot the data from the data table. Surround each point with a small circle and connect the points. [1]

- Obtain data points from the table:

| Temperature (°C) | Gill Cover Openings Per Minute |
|------------------|--------------------------------|
| 10 | 15 |
| 15 | 25 |
| 18 | 30 |
| 20 | 38 |
| 23 | 60 |
| 25 | 57 |
| 27 | 25 |

- Draw these points on the graph and connect them in sequence with straight lines.

#### Analysis:
4. According to the data, as the temperature increases, the rate of respiration of the sunfish:

- Observing the data:
- From 10°C to 23°C, the rate of respiration (gill cover openings per minute) increases from 15 to 60.
- From 23°C to 27°C, the rate of respiration decreases from 60 to 25.
- This observation tells us that the rate of respiration increases up to a certain point (23°C) and then decreases.
- Therefore, the correct answer is:
(3) increases, then decreases

5. Which title is appropriate for this graph?

- The graph aims to show how temperature affects the rate of respiration in sunfish.
- An appropriate title would directly address this relationship.
- Therefore, the most suitable title is:
(1) The Effect of Temperature on Rate of Respiration in Sunfish
