Base your answer to the question on the information, diagram, and data table below and on your knowledge of Living Environment.

The laboratory setup represented below was used to investigate the effect of light on aquatic plants. Equal amounts of a green water plant were placed in beakers with gas-collecting tubes. The beakers were placed in a temperature-controlled environment. The light source was placed at different distances from the beakers. After an hour, the amount of gas collected from the plants in each tube was measured and recorded in the data table.

A. Using the information given, construct a line graph on the grid following the directions below. MUITLPLY CHOCIE
1. Provide an appropriate label for the y-axis, including units, on the line provided.
2. Mark an appropriate scale, without any breaks in the data, on each labeled axis.
3. Plot the data on the grid, connect the points, and surround each point with a small circle.

B. Row Independent Variable Dependent Variable (muitlply chocie)
1. amount of gas collected distance of beaker from light source
2. number of plants in the beaker temperature of plant
3. distance of beaker from light source amount of gas collected
4. minutes of exposure to the light source rate of gas collection

5. State the relationship between the distance from the light source from the plant and the amount of gas collected.

B) When defining variables, the correct option is 3. Distance of beaker from the light source (independent) / amount of gas collected (dependent). C) There is an indirectly proportional relationship between the variables.

-------------------------------------

Based on the table information, we can assume that the more distant the lamp is, the less amount gas is produced by the plants and, hence, collected in the tubes.

A- Line Graph

We need to construct a graph illustrating the data in the table.

To do so, first, we need to define the dependent and independent variables.

• The independent variable affects the response of another variable.

The independent variable is the distance of the light source.

The change in distance affects the photosynthetic rate, measured through gas collected in the tubes.

• Dependent variable depends on any change in the independent variable.

In this experiment, the dependent variable is the amount of gas collected, which reflects the photosynthetic rate.

This variable depends on the distance of the light source.

Knowing this, we can graph both axes.

Horizontal ax ⇒ X ⇒ Independent variable ⇒ Distance of light source from the plant ⇒ Units: cm

Vertical ax ⇒ Y ⇒ Dependent variable ⇒ Gas collected in the tube ⇒ Units: mm

Remember to label each of the axes and to specify units.

You can place units in every single value on the axes or in the ax label.

Units are,

mm ⇒ for the gas collected in tubes ⇒ Y ax

cm ⇒ for the distance of light ⇒ X ax

B. Now, we need to define the variables.

As we said before,

The independent variable is the distance of the light source, which influences the amount of gas produced by the plant and collected in the tubes.

The dependent variable is the amount of gas collected, which reflects the photosynthetic rate. It depends on how distant is the plant from the light source.

The correct option is 3. distance of beaker from the light source (independent) / amount of gas collected (dependent).

C. Relationship between variables

The dependent variable can express two types of relationship with the independent variable,

directly proportional relationship means that as the independent variable increases, the dependent variable increases too.

indirectly proportional relationship means that as the independent variable increases, the dependent variable decreases.

The exposed experiment shows the indirectly proportional relationship between the distance of the light source and the amount of gas collected.

The farther the light is placed, the least amount of gas is collected in the tubes.
