Daphnia Lab Quiz Flashcards
1
Q
What is the independent variable in the experiment?
A
test solution that daphnia was put into
2
Q
What is the dependent variable?
A
daphnia heart rate
3
Q
How will you graphically represent the combined data from the experiment? Which variable
should be on the x axis? The y axis?
A
Graph could be heart rate versus time in certain solution
y-axis = heart rate
x-axis = time in solution

Q
What effect (if any) will ethanol have on the heart rate of Daphnia?
A
decrease heart rate, stronger concentration = more significant decrease
5
Q
What effect (if any) will caffeine have on the heart rate of Daphnia?
A
increase heart rate, stronger concentration = more significant increase
