Graphing & Microscopes

What is the purpose of graphing independent and dependent variables?

• To make the graph look pretty

• To visualize and understand the relationship between variables.

• To waste time

• To confuse the reader

What are the x and y axes in a graph used for?

• The x-axis represents the horizontal axis and the y-axis represents the vertical axis.

• The x-axis represents the input and the y-axis represents the output.

• The x-axis represents the dependent variable and the y-axis represents the independent variable.

• The x-axis represents the independent variable and the y-axis represents the dependent variable.

Define carrying capacity in the context of graphing.

• Maximum number of individuals or entities that a graph can represent or accommodate

• The number of lines on a graph

• The number of data points on a graph

• The range of values on the x-axis of a graph

How do you identify the independent variable in a graph?

• The independent variable is the variable that remains constant throughout the experiment.

• The independent variable is the variable that is measured or observed in the experiment.

• The independent variable is the variable that is manipulated or changed by the experimenter.

• The independent variable is the variable that is determined by the dependent variable.

What is the dependent variable in a logistic graph?

• The independent variable

• The y-axis

• The slope

• The x-axis

Give an example of a real-life situation that can be represented by an exponential graph.

• Population growth of humans

• Compound interest

• Temperature change over time

• Linear population growth

How does carrying capacity affect the shape of a logistic graph?

• Carrying capacity causes the graph to be linear.

• Carrying capacity has no effect on the shape of a logistic graph.

• Carrying capacity results in an exponential growth curve.

• Carrying capacity determines the maximum population size and results in a sigmoidal or S-shaped curve.

What is the magnification of a microscope if the objective lens is 10x and the eyepiece is 20x?

• 30x

• 20x

• 200x

• 10x

Which adjustment knob should you use first when focusing a microscope?

• Fine adjustment knob

• Coarse adjustment knob

• Lens adjustment knob

• stage adjustment knob

When focusing a microscope, which objective lens should you magnify with first?

• low power objective lens

• medium power objective lens

• high power objective lens

• oil objective lens
