Biology EOC Review and Biological
Principles 132 questions and actual
answers.
List and describe the steps of the SCIENTIFIC METHOD - ANSWER •Observation- thoughtful and careful
recognition of an event or a fact
• Hypothesis- propose possible solutions to question based on what is already understood, must be
testable
• Experimentation- test if the hypothesis can be supported or rejected
•Repeat experiments
Why do many experiments make use of a control group? - ANSWER Something to compare to
What are the characteristics of a good experiment? - ANSWER Many tests, all parts of an experiment
present
What is the difference between an inference and a prediction? - ANSWER Inference = based on
observation
Prediction= is a hypothesis
What are the differences between hypothesis, theory and law? - ANSWER Hypothesis= educated guess
Theory= based on experiments
Law= proven the same over and over
What is the differences between an independent and dependent variable? - ANSWER Independent
Variable= things you test or change
Dependent Variable= things you measure

Interpret graphs. Which axis has the independent variable? Which axis has the dependent variable? -
ANSWER Independent Variable= x axis
Dependent Variable= y axis
How do you determine the magnification of the field of view for a microscope? - ANSWER Power of lens
Power of objective= magnification
What happens to the diameter of the field of view when you change from low to high power? - ANSWER
Less to high magnification
How do you estimate the size of a cell or a cell structure when using a microscope? - ANSWER Consider
magnification and original size
What do you adjust first on a microscope? What do you then adjust when on the highest power? -
ANSWER 1. Course adjustment
2. Fine adjustment
You have measured the rate at which a fish breaths at various temperatures by counting the rate at
which its gills open, the data is below graph data. - ANSWER Breathing rate temperatures:
19/ min 5°C
25/ min 10°C
30/ min 20°C
34/ min 30°C
37/ min 35°C
What is the independent variable? The dependent variable? - ANSWER Independent = Temp.

answers.
Dependent= Breathing rate
What is the best type of graph for this data? Why? - ANSWER Line graph because it shows trends
What happens to breathing rate with increase in temp. ? - ANSWER Increases
What would be a good control for this experiment? - ANSWER Temperature stays the same and measure
How do you think the breathing rate was measured? - ANSWER Breaths permanent
What do you think if you raised the temperature even more? - ANSWER Increase in breathing rate
Why would it be a bad idea to do this? - ANSWER Could kill the fish
Looking at the graph what conclusions can you draw about algae growth and nitrates in the water? -
ANSWER There is a variation of conclusions = inconclusive
What other data would you like to have ? - ANSWER Population of bacteria with percent of transmission
or nitrates
What would you predict would happen if this same data was gathered at the end of week 8? - ANSWER
Decrease in percent of transmission
Why do you think that nitrates have this effect on algae growth? - ANSWER Algae is able to grow due to
a need of nitrates biologically
What kind of care must be taken when working with bacteria? Why must care be used when working
with bacteria? - ANSWER Cover body as to not ingest
